Modafinil Not Working? | Here’s What You MUST Do

Modafinil not working?

Then you’re in the perfect place. Never fear, though. Below you’ll find out exactly how to make Modafinil work for you. For certain users, the smart drug’s effects may not be felt instantly. While this is rare, it does happen…and there are solutions.

I remember the first time I couldn’t feel Modafinil “kick” in. I’d been at home popping pills for a solid two months building a few websites. I was taking Modafinil 4-5 days a week at higher dosages. 200-400mg was common for me.

On average, I was taking 1,000-1,200mg of Modafinil each week for nearly two months. Towards the end of these two months, I started feeling less and less each time I took Modafinil. Eventually, I couldn’t “feel” Modafinil unless I took 300mg in one dose.

Is Modafinil not working? Or had I just screwed my tolerance up completely? The smart drug wasn’t working like it used to because I was taking too much.

However, here’s the thing…

Users who cannot feel the effects of Modafinil tend to fall into two camps. The first camp is new users who are non-responsive. The second group of people who can’t feel “Modafinil” are long-term users who have damaged their tolerance through consistent use and high dosages. There’s solutions for individuals who fall into both camps.

Below we’ll discuss the following:

Modafinil not working

P.S.: This is not medical advice. I am not a doctor or medical professional or a lawyer. Always consult a doctor before taking any prescription drugs or nootropic – like Modafinil. And make sure to read my disclaimer page before moving forward.

What is Modafinil?

First, what is Modafinil? I have a feeling you know about the smart drug if you’re reading this. But for those who don’t:

Modafinil is a pharmaceutical drug that was created as a wakefulness agent. When taking Modafinil, one should be unable to feel fatigue or fall asleep.

Originally designed in France, Modafinil is used to treat common disorders like [1]:

  • Narcolepsy
  • Sleep apnea
  • Shift sleep disorder

However, you may not be curious why Modafinil doesn’t work if you have one of the conditions above. There’s a good chance you’re curious about the cognitive effects of Modafinil. Aka using Modafinil as a smart drug and/or nootropic.

That’s because Modafinil has become that’s become popular with grad students, startup CEOs, and entrepreneurs of all stripes. Why? Because Modafinil has been proven to [2]:

  • 12+ Hours Focus
  • Increased Alertness and Wakefulness
  • Long Attention Spans
  • Increased Productivity
  • Heightened Concentration
  • Improved Cognition

That’s just the tip of the iceberg!

Staying focused for 12+ hours allows anyone and everyone to get a step ahead of the competition. To get more stuff done. To make more money. To get better grades. Whatever.

It’s exactly why Modafinil is the world’s most popular smart drug.

Modafinil just works.

Modafinil Side Effects and Safety

Before we talk about why Modafinil is not working for you, let’s discuss a bit about Modafinil side effects and safety.

Listed below are a few common side effects of Modafinil, including [3]:

  • Headache
  • Trouble sleeping
  • Insomnia
  • Nausea
  • Diarrhea
  • Dizziness
  • Agitation
  • Dry mouth
  • Nervousness
  • Anxiety

While users need to be concerned about Modafinil side effects and safety to a certain extent, the reality is the vast majority of users taking Modafinil as a smart drug experience few side effects.

Modafinil is a safe cognitive enhancers for nearly everyone. Various research studies have concluded nootropics are safe overall. Yet further research is warranted, as the smart drug craze is a newer phenomenon…especially with regards to the mechanism of action. Long-term effects are also relatively unknown.

There was a study done by the Korean Society of Environmental Health and Toxicology which concluded [4]:

Modafinil is known to have less or no adverse effects than those found in traditional psychostimulants such as amphetamine, methylphenidate or cocaine. It can be applied as an anti-psychotic or anti-fatigue agent. However, the waking mechanism of modafinil is yet to be fully revealed. Recent studies reported that modafinil may be subject to abuse and addiction. In addition prolonged sleeplessness induces stress responses and impairs immune function.

Modafinil can be used by anyone, who wishes to work late, stay awake, enhance their cognitive reactions, or brighten their moods. Users may already be under a great level of stress, i.e. cancer patients or soldiers in a battle field. A psychoneuroimmunological approach is thus needed to investigate the multi-functional effects of modafinil.

In layman’s terms, Modafinil is a safe cognitive enhancer for already healthy individuals. Mild side effects may be noted, but they are rarely, if ever, severe.

Plus, there has yet to be a death from Modafinil due to a bad reaction or overdose. Not a single one!

As such, it’s fair to say Modafinil is 100% safe for the majority of users. Although, it must be noted again, that I am not a doctor and this is not medical advice.

Modafinil Not Working | For New Users?

So if you’re taking Modafinil for the first couple times and it’s not working.You feel nothing. No cognitive enhancement. No energy boost.

What do you do?

The reality of the situation is Modafinil doesn’t work for some people. That’s true for any prescription drug. Some people just don’t respond to it.

However, I’d venture to say 95-98% will respond to legitimate generic Modafinil.

While that’s certainly not scientific, I’ve yet to hear of anyone who just couldn’t feel Modafinil when taken and dosed properly. If you don’t feel anything, there are a few things you can do before you give up on the nootropic.

Before doing anything, individuals will want to try out a “test” to see if they’re responding to Modafinil or not. Below you’ll find the test one can run to determine how responsive they are to Modafinil.

The Test

This test is not scientific. However, it does work. You can test your reaction to Modafinil. Well, at least to a certain degree.

Here’s how you do it:

  • Step #1: Set your alarm clock for 5:30am.
  • Step #2: Place an unopened 200mg Modafinil tablet on your bed stand with a water bottle. Put a small granola bar there too.
  • Step #3: Try to get to bed early. You want to get 5-7 hours of sleep before that alarm clock goes off.
  • Step #4: When the alarm clock goes off, eat the granola bar and take a swig of water. Open the Modafinil tablet and take it. Drink 6-8 ounces of water. Don’t drink the whole bottle. Just a bit.
  • Step #5: Do NOT turn on any lights. Do NOT get out of bed. Go straight back to sleep. Make sure your room is pitch black, no light coming in.
  • Step #6: Let your body wake up naturally. No more alarm clock. No light. No noise.

If you wake up within 90-180 minutes after taking the Modafinil, aka within 3 hours, and your mind is kicking, you feel energy. You’re ready to conquer the day…

Then the Modafinil is working. 100%.

If you feel groggy and tired still, there’s only three things that could have happened:

  1. You’re not responsive to Modafinil.
  2. The Modafinil is not legitimate.
  3. You need to drink a cup of coffee.

Before digging deeper into this issue, there’s a few things to note:

First, users should not try this test on their first time taking Modafinil or with a new batch recently ordered. Take Modafinil normally to start. Only use this test if you’re not feeling anything after a few times taking nootropics.

As well, healthy individuals with IQ levels above 135+ have reported struggling to feel the effects of Modafinil more than most. If you’re a legitimate genius, Modafinil may be a crapshoot.

However, many highly intelligent people, including doctors, CEOs, and even USA Presidents, all use Modafinil with great benefit.

No matter what, there are solutions…

Below we’ll discuss how to make Modafinil work for you — if you can’t feel the effects as a new user.

Modafinil Not Working | For Long-Term User?

If Modafinil has worked for you in the past, then you’re responsive to the drug. That’s good news.

Generally, this means you’re having one of two problems:

  • You’ve taken too much Modafinil and your tolerance is screwed up.
  • You’ve purchased a bad batch of Modafinil from a non-legitimate vendor.

For individuals who have taken Modafinil too much, especially as a nootropic, tolerance levels can get screwed up and effects may not be felt. Luckily, that’s an easy fix.

If your Modafinil tolerance levels are out of whack, here are a few things to do:

  • Stop taking Modafinil for one week to one month.
  • Cut back on Modafinil. Only take the smart drug 1-3 times a week. 
  • Only take 200-300 mg of Modafinil. Some users take 400-500 mg, but that’s just too much for most users on a long-term basis.
  • Combine with this gum when you start using it again.

If you’ve taken Modafinil daily for months on end, the most important step is taking a break from Modafinil. Seriously! Stop taking Modafinil for a month and your tolerance levels are sure to come back to normal.

It’s that simple.

However, if you’re taking Modafinil for narcolepsy or sleep apnea, then it might be a little more complex. If you’re taking Modafinil for off-the-label uses like cognitive enhancement, then taking a month off from Modafinil is what you’ll need to do.

The other issue could be…

You bought fake Modafinil.

While there have been varying reports of fake Modafinil shipped from overseas all over the Internet, it’s fairly easy to find legitimate online Modafinil pharmacies these days.

As of writing, this is the best online Modafinil vendor in the world.

You’ll get 100% legitimate Modafinil and Armodafinil products when purchasing from the vendor above. I’ve personally purchased from them multiple times with great success.

P.S: Try out a sample pack for that vendor…if you want to test a bunch of nootropics!

If you think the Modafinil you’ve purchased is fake, you could pay a laboratory to test for the R-(−)- and S-(+)-enantiomers [5] in Modafinil — the active ingredients. If testing Armodafinil tablets, the nootropic only features one of these “active” enantiomers: R-(−)-Modafinil [6].

However, testing the authenticity of any batch Modafinil will be far more costly than simply ordering another batch.

Home testing methods to verify the authenticity of Modafinil don’t really work. You can’t just drop it in water and wait for it to dissolve. That’s far from accurate!

For those technically inclined with a biology/chemistry background, you could purchases a Thin Layer Chromatography test kit. Other individuals have attempted to test the authenticity of their Modafinil batch with this method.

However, this testing kit will generally cost more than ordering Modafinil again.

Interactions with Other Compounds?

Both new users and long-term users of Modafinil could face one other issue when Modafinil is not working.

While this is fairly uncommon, it should be noted that:

Modafinil can interact and interfere with other compounds, which can lead to a lack of cognitive benefits.

When taking Modafinil, most users experience an absorption rate around 60% once ingested [7]. Yet when individuals take other supplements and medications at the same time as Modafinil, this can interfere with the absorption. Meaning you’ll get less benefit from the Modafinil.

If you’ve been struggling to “feel” Modafinil, try only taking the nootropic by itself. Do not take any other supplements and/or medications on days you’re taking Modafinil…if you’re taking Modafinil as a smart drug and haven’t been feeling the effects.

For example, these foods and supplements have been shown to interact with various medications, including Modafinil:

  • Antacids
  • Fiber supplements
  • Licorice
  • Activated charcoal
  • Tea

This list is certainly not exhaustive, but may give you an idea of something you’re taking or eating that may be causing issues with Modafinil absorption.

The easiest way to fix this potential issue?

Take Modafinil 30 minutes after a light, healthy breakfast in the morning. Do NOT take any other supplements or teas when taking the Modafinil. Wait another 30 minutes and then drink some coffee.

Make Modafinil Work For You

For individuals who believe they’re responsive to Modafinil, but haven’t been getting the results they’re looking for, I’ve got a few suggestions.

Here’s a few of the variables to consider when switching things up:

  • Up the Dose: A typically Modafinil dose is 200mg. If you’re only taking 100mg or less, you may not feel much. If 200mg isn’t working, you can try out 300mg. This is especially true for individuals with higher body weight. Going over 400mg is not recommended when using Modafinil as a smart drug.
  • Split the Dose: Another trick is to split 300mg of Modafinil into one 200mg dose and one 100mg dose. Take the larger dosage in the morning early and the second 100mg dose around noon. This can help boost the effects of Modafinil, especially when hitting a plateau.
  • Don’t Wait: Don’t wait for the Modafinil to “kick” in. Take the smart drug and get to work. Often, I don’t feel Modafinil until I look at the clock and realize I’ve been working without a break for 3-4+ hours. Have a plan ready to go!
  • Combine With Coffee: Take 200mg of Modafinil and then down a few cups of coffee 30 minutes later. Caffeine mixes well with smart drugs and can help the nootropic effects kick in forcefully.
  • The Next Level: If you’re committed to feeling something no matter what, you can chew on these after taking Modafinil. You’ll definitely feel something. I guarantee it. This isn’t for the faint of heart.

All the above should ensure you get maximum benefit from Modafinil usage.

Personally, I often combine 200mg Modalert with multiple cups of coffee and nicotine gum. This gives me crazy intense focus and productivity.

Thiago Diniz - August 5, 2017

Hey dude, give a help here… I use Modafinil however I have been taking anxiolytic.
1- I stop to take anxiolytic two days before to take modafinil.
2- I take modafinil for 2 days (200 mg each day), and then I back to anxiolytic
I do that once a week to study.
The frist time works. The second time stopped to work. what I have to do?

    NomadicJake - August 6, 2017

    Hmmm, I’m not sure, man. You’re saying the first day you take 200 mg of Modafinil it works and the second day you take 200 mg it doesn’t?

      Thiago Diniz - August 6, 2017

      Thanks for reply man..
      Yes… that it!

      1* day. 200 effect
      2* day 100 effect

      Pass one week

      3* day 100 no effect
      4* day 100 no effect

      Pass one week

      4* day 200 no effect
      5* day 400 no effect

      Can u believe that?

      All off then was the same vendor.

        NomadicJake - August 7, 2017

        Also, give the test I wrote about above a shot. You may not be responsive, but this will help you find out.

          Thiago Diniz - August 7, 2017

          But works ttwice… for me thats sounds most stranger.

          NomadicJake - August 7, 2017

          Agreed, It’s definitely strange. Did any other variables change between when it worked and when it didn’t? Diet? Exercise? Timing? Caffeine?

          Thiago Diniz - August 7, 2017

          Man… I don’t know. I didint notice. Maybe the breakfast.
          I will try take the pill with the empty stomach.

          NomadicJake - August 7, 2017

          Yeah, I’d give that a shot first and see what happens. Certainly an interesting case here.

          Thiago Diniz - August 7, 2017

          I will take a rest… one or two weeks off, and then, I will do that! Thanks bro… if something comes out in your mind, let me know!

          NomadicJake - August 7, 2017

          For sure! Good luck, bro

          Japneet Singh - November 13, 2017

          Same thing happened with me did u find a way around

        Varun - March 7, 2019

        i have the same situation, medofilin worked for 2 days to me 100 mg and 200mg respectively but after that it is not working at all.
        i even increased the dosage gradually

      Thiago Diniz - August 7, 2017

      Can you help tp understand? I am not non response. I guess the problem is in my mind, I am creating a lot of expetantions arround this medication. i dont know…

        NomadicJake - August 7, 2017

        Hmm, that’s interesting that it worked well for you twice and then tolerance kicked in.

        I’d lay off it for a full-month and then try again. Maybe see if taking it on an empty stomach helps.

        You could also up the dosage to 300 mg if you want to push it.

        I’d also drink a ton of coffee when you take it.

        Other than that, it seems to be a bit odd. Most people who are non-respondents don’t feel anything the first couple times.

    Alline Tropp - February 5, 2019

    Hi there, great post! I have a question I was hoping you might be able to help with. Can you treat ADHD without drugs? My doctor mentioned that I might have it but I’m not so sure. A really appreciate any advice you can give.

      Jake - February 5, 2019

      I’m no doctor!

      But I’d avoid taking anything for ADHD…unless you 100% have it.

      People who truly have ADHD generally bounce off the walls. It’s not a “might have it” type of thing in my mind. Again, I’m not a medical professional.

      I could be off base here.

      That said…

      On days you must focus, Modafinil can help.

      A daily natural nootropic stack of CBD oil, Vitamin D, and SAM-e may be beneficial for focus.

        Kelly - February 23, 2019

        Kindof. I have mixed ADHD I have been arrested several times for “bouncing off walls” it was that bad but on the other hand I was like a vegetable a lot too. Adderall is the only thing that helps, now I need something for my sleep aphnea as I can barely stay awake 🙁

          Jake - February 25, 2019


          That’s an interesting mix of issues you got going on here.

          Hope you can figure it all out.

BarbaraThe - November 13, 2017

I started Modafinil on Friday. 100mg in a.m. next 100mg at noon. First day I had a burst of energy at 8pm. Nothing ever since. Even now after this second dose, I want to take a nap! Must be that IQ of mine! I’ll give it a couple weeks, but my next option is probably Adderall.

    NomadicJake - November 13, 2017

    It’s gotta be that IQ 😉

    I’d try the test mentioned above. If nothing, then maybe you’re a non-responder.

    Upping the dosage to 200-300 mg at one time could work. BTW, where did you get your Moda from?

G_Amsterdambuhd - October 6, 2018

“up the dose especially if you’re a larger person” – I am.. big dude 375 – took 200mg first time ever, felt nothing , took 100mg an hour later… then I took the other half an hour after than.. My first time ever…. I was HAPPY all day and HAPPY TO WORK!!! My shift blew by so quickly, I was so excited, and was like YES I can get through this job, I have a secret…… WELL.. that was the last I’ve felt of the modafinil. I don’t feel that ‘I’M GONNA HAVE SUCH A GREAT DAY’ feeling.. I wasn’t zoned my first time,, I did stay longer at my desk and wasn’t distracted, but def not tunnel vision. I just felt like taking and more and calls to interact with these people. OMG.. felt so good. Now, I take the modafinil… I’m back to feeling distracted as hell, agitated that the time is moving slowly, but the only thing that get from the modafinil is i’m not sleepy at all, bored, distracted and can’t sleep is pretty bad. After my first day I skipped a day since I was off from work, but i’ve been popping 600mg @7am and i’m not getting that HAPPY TO GET WORK feeling like the first time. So I can’t be a non respondant , since I did feel it.. What the hell happened? What’s the max mg I can safely take? Again, i’m 375lbs. Help me get back that first feeling, please.

Co. Semel - October 9, 2018

…interesting, there is a pattern here! My experience:
– first time 100mg everything is great, mood fine, focussed, getting a lot done.
– second and third time (2 days later), dosis 50mg and 25 mg, effect less pronounced (as was to be expected and also desired), but still feeling it kicking in and working in a subtle way.
– every dosis since (again 2-3 days later, 25 – 50 mg) no more positive effects, quite the opposite. Even 25 mg cause dizzines and drowsy spells and occasional light headaches for roughly 36h. Mental and physical performance are def. compromised. The only good feeling I get, is when it has been flushed out of the system. I guess this is the end of the road for me and Modalert.

    Jake - October 10, 2018

    Interesting to say the least.

    Have you tried Waklert yet?

    I’ve definitely noticed fewer side effects with Waklert than anything else as of late.

      Co. Semel - October 10, 2018

      Yes, I did try it once, …75mg. It was stronger and more neutral moodwise than Modalert, just like most people are saying. Didn’t feel any neg. side effects then, ….don’t know, maybe because I took the Waklert dose before Modalert stopped working for me, other than making me dizzy etc. I am quite reluctant to give it a try now, because it is metaboilzed into Modalert, afaik, isn’t that right?. Might give it a shot though in a month time … not sure. The last experiences were pretty bad.

        Jake - October 10, 2018

        Waklert only has one of the compounds found in Modalert – not both of them.

        As such, it’s a more “pure” version of Modalert.

        Some find Modalert is stronger, but most find fewer side effects with Waklert.

        Not saying it’s the ideal solution for you, but could be.

        Sucks you’ve had such a bad reaction, as that’s fairly rare.

          Co. Semel - October 10, 2018

          …ok, I didn’t know that. I thought Modalert is basically 1st Modafinil for the initial response and 2ndly the Waklert stuff which is metabolized to Modafinil, taking some time and as such kicking in later. If and when I’ll try Waklert again, I’ll come back with an update regarding effects/side effects. I am actually quite curious.

Mari - December 5, 2018

Crap! I have adult ADHD and have taken a daily dose of Ritilan of 120mg per day for 30 years. I also suffer from PTSD and Depression and have very low energy so while the Ritalin gives me locomotion, I always want a clearer and sharper mind. I tried Modafinil for a month, staring with 200mg dose and after no noticeable result, quickly doubled and doubled that. Then I gave up. Now despite what my psychiatrist codifies as a “severe” learning disability, I am a member of Mensa and tested in the high 140’s. For some reason, I suspected the inefficiency was a result of my IQ. Now I feel totally defeated. Ah

    Jake - December 5, 2018

    The good news is you’re so smart you needn’t smart drugs to get a cognitive boost, though…

    That’s a win if there ever was one!

    But yeah, if 200 mg of Modafinil doesn’t work from you at the beginning, then I wouldn’t up things.

Charbel - March 26, 2019

Hey, today was my first time trying modafinil, i took modalert 100mg which i felt it kick in after aprox. 40m on an empty stomach, but the thing is after almost 3hrs the effect faded away and i felt sleepy, is that normal?

    Jake - March 28, 2019

    No, I’d say that is not normal.

    I recommend trying the test above next time and seeing what happens.

    Could also up the dosage and add coffee.

Dion Dangerfield - May 24, 2019

I have taken all the tests and I wouldn’t call myself a genius and I’ve been taking 400mg everyday and I have had no effects! What do I do

    Jake - May 26, 2019

    Honestly, I have no clue.

    Where did you get the Modafinil from?

just had 100mg from prescription the first time today 2hrs ago. Not sure if im feeling too much but will give another 2hrs. I am 93kg so may try 200mg tomorrow if not working out

    Can take more than a couple hours to really feel it, especially on a lower dose.

    200mg for 93kg should also be fine. Just make sure to take it in the morning followed by a cup of coffee 30 minutes later.

Same for me
First time it was Amazing, great feeling, great mood, focusing on everything, so good at everything i was doing, and after that…
(2days laters) No Effect at all, just a little boost like caffeine Does, anxiety, Headhach

    It’s always odd when this happens, but the best recommendation I can give you is to try the test above upon waking. And see if you notice any effects then.

Hi, i have some questions.
So first of all i enjoy taking modafinil (modalert)
took it for a couple of weeks and always had a great experience.
i once tried Armodafinil (waklert i guess) but it was a little more subtle than modafinil but i could not sleep at all, so no more armodafinil for me. Modafinil definitely words fine on me (mostly i just take one pill of 200mg), but i have the strange feeling that taking 100mg 2 times is better. BUT last weeks when i’m taking it, i feel it works but i feel tired on it.
i only take this while studying for a month (5 days a week for like 6 weeks twice a year)
i’m 85 kg / 187 lbs
i take SSRI for anxiety disorder and that might explain a lot, but the problem is, i do feel tired but my heart stays at an increased rate, so what is your advice? i never took more than 200mg and a quarter so 250mg of modafinil.
I only take it for studying purposes

    Jake - December 17, 2019

    That’s a bit difficult and I’m certainly no doctor. However, the addition of an SSRI makes things a bit more tricky.

    I’d try going 2 days on, 1 day off when studying like you do — and only doing 4X a week.

    I’d up coffee intake, add a Vitamin D supplement, add a SAM-e supplement, and make sure you’re pretty healthy outside of the Modafinil. Aka getting great sleep, hitting the gym on non-Modafinil days, eating clean, and all that stuff. Try to get some sunlight on non-Modafinil days too.

I actually take Modafinil for a medical reason, but I find myself on these nootropic websites because I find some good information about the drug. Modafinil has never really done much for me, even when I first started taking it. It gives me a little boost, but I can easily take a nap after taking it. I would be interested in the pharmacology around the drug that makes someone less responsive to the drug. I do have an IQ above 130, but I’m trying to use it to stay awake, not to enhance cognition.

    Jake - December 27, 2019

    Does Modafinil not help you stay awake and alert even at higher doses? While I can’t comment too much on taking Modafinil for medical reasons, I know many people who take it and find it impossible to sleep — even at night.

    Is your diet and lifestyle fairly clean outside the Modafinil usage?
