For Narcolepsy "The first one I tried, and it was not good for me. The constant headaches, dry mouth (very bad at nighttime), made me have very real-like/scary nightmares, and after 2 days did not even change my energy level/random sleep attacks. Still had to have a nap to make it through the day."

For Narcolepsy "Provigil (Modafinil) has been a good addition to my regimen for dealing with the symptoms of narcolepsy. I take different doses depending on the severity of symptoms. I take 50 mg twice a day most of the time, or 100 mg twice a day. I have tried 200 mg once or twice a day, and that's where the side effects kick in (very dry mouth and headaches). It does keep me awake during the day most of the time, but sometimes I feel as if I never took it. But that's where adding coffee or caffeine pills really helps. I feel safe taking this med, and I'm happy to have discovered it."
