Modafinil for cognitive neuroenhancement: a systematic review 11 years ago
I started taking Modafinil 3 months ago because I had to start a job which would be new & kind of difficult for me, and my prior "normal" routine involved getting really sleepy in the afternoon (yes, I was getting proper 7-8 hrs at night) and taking a nap, which wouldn't be possible at the new job.
In short, it works. I have been taking 200mg doses. I don't notice any focusing effect. I just don't get sleepy, at all, during the day. Only other effect, for me, is caffeine sensitivity -- as other posters have noted, modafinil will not make you feel wired, but add half a cup of coffee and there you go, if that's your thing.
