I've been taking Provigil for about 4 years for MS Fatigue. It works quite well. I can honestly say that I could not get through the day without it.
I take between 200-400mg per day every day. And I also drink 3-4 cups of coffee a day (not DECAF either). I don't drink soft drinks, just coffee.
Here's a link from the NMSS website with some information about Provigil (modafinil).
