Hi All, Just posting my recent experience with taking Modafinil (Modvigil) for the first time. Some initial background. I have been using experimenting with Nootropics for about a month. I have a daily stack that includes a few vitamin supplements, fish oil (omega 3/EPA/DHA), Lions Mane, Choline/Inositol (500mg) and Piracetam (2.4mg). Over the course of 3 weeks I noticed a good improvement in cognitive functions (short-term memory, recall, clarity, focus). Yesterday I woke up at 6am (after going to be at 12:00am), then snoozed in bed until 9am and when I finally woke up I felt very groggy. At around 10am I decided to try some modafinil (Modvigil) that I purchased a number of weeks ago. I took one capsule of 200mg. I also decided not to take my usual stack (as mentioned above) except for 500mg of Choline/Inositol and 500mg of Lions Mane. Effects In the first hour I felt no effect, by the second hour I felt more awake and could focus on some work. It definitely had an effect on my appetite and I had to force myself to eat some food for lunch. After about 3-4 hours I started to have a dull ache in the front of my head. However I could still concentrate and obsessively dismantled my espresso machine (took around 3 hours), something I wanted to do for a while. By 16:00 the dull ache became quite a bad tension headache, although I could still think clearly. I had to go and lie down in a dark room. At this point I decided to take some ibuprofen/lysine, a quick search on the net yielded no negative experiences of ibuprofen combined with modafinil. At 20:00 the headache had subsided to a dull ache and I could feel the effects of the modafinil wearing off, I felt more mentally tired. I went to bed at 22:00 but had trouble sleeping, so took 5mg of melatonin and was out within 15-20 minutes. Actually had some very vivid dreams, most of which I can remember this morning. Obviously headaches are a potential side-effect of modafinil but I do occasionally get headaches if I have limited sleep (<6hrs) or have not drank enough water. Yesterday I had about 6hrs sleep, and I drank some water, but not my usual amount. I also avoided stimulants including caffeine (as coffee). My plan is to try modafinil again, but after a full 7-8hrs sleep. I am hoping that the headache was an anomaly, I would also like to try a higher dosage of 400mg, but may do this after a test run at 200mg to make sure there is no correlation between modafinil and my headache.
