narcolepsy
"I have been diagnosed with narcolepsy, cataplexy, and fibromyalgia. I was on Provigil and Adderall, and still falling asleep. Doc started me on 2.5 mg twice a night. I was sleeping. At night only! I am on 3.0 mg now, and still taking the Adderall during the day. I am not falling asleep at work, and my cataplexy and  hallucinations are almost nonexistent! I still get tired pretty early on in the evening, but I was starting to worry about my ability to continue working. It also seems to be helping with the pain. I get nauseous sometimes during the day, but have found that it's because I need to drink some water or eat something. I feel like the old me again. I just hope the insurance doesn't decide not to cover it."
