How safe is it to take Modafinil daily?
It's quite safe in low doses. I'm a programmer consultant with 2 businesses, and regularly do 12–14 hour days 6 days a week. Most days, I take 50mg modafinil after lunch so I don't get food comatose, and can keep going sharp straight to 9–10pm. On some days, I will even take one 50mg dose early morning, and another 50mg mid afternoon. There are, however, drawbacks from my experience. After so many days in a row, you may start to feel easily irritated, and for me at least, 2 days after you stop, there's definitely a kind of brain lethargic effect (as with stopping any regular stimulant, like a daily coffee habit, etc.). However, compared to caffeine, modafinil doesn't give you a spike in stimulation and the crash, it's much more even keel and definitely lasts a lot longer (all day long in my case). Every few weeks, I'll take a solid week break to let my brain reset, and definitely one to two full days off a week to reset my system. Ah yes, one other side effect that some users report, including myself, it induces bowl movement, and if taken too many days in a row, diarrhea; so take plenty of water while you do. Hope this helps!
