I've been on Modafinal (Provigil) for 8+ years. I have Excessive Daytime Somnolence (sleepiness) and I'd have a hard time functioning without it. I take one or two 200mg tablets each day, depending on how I'm feeling (usually just one). I still remember the first few days I was taking Modafinal: I felt like I could see in 360-degrees. I was super alert. That effect wore of quickly. Now, most days when I take Modafinal, I feel alert and ready to work; not perfect but much much better than before. Sometimes the effect doesn't kick-in. When this happens for more than a week in a row, I stop taking it for a few days. When I restart, it seems to kick back in. I see my doctor regularly to make sure everything is okay. I have noticed no strange side effects other than my up-coming Noble prize in astrophysics, my solution to N = NP, and my Sudoku solver written Brainfuck (http://en.wikipedia.org/wiki/Brainfuck http://en.wikipedia.org/wiki/Brainfuck). Personally, I would not recommend using Modafinal without the supervision of a doctor. It's also expensive, even with "good" health insurance.
