Narcolepsy
"Provigil worked for my narcolepsy for about 6 months. After that, I began to have bouts of insomnia at night and became ultra sleepy during the day times. I was prescribed sleep medications to help combat the new side effects. Things did not seem to improve. I also gained 40 pounds during the time I took Provigil (which was a total of 9 months). As a woman, gaining weight was my LEAST desirable side effect of all. Finally, I switched off of Provigil and returned to what was working for me originally, Adderall XR 30 mg one to two times per day (depending on what my schedule was like that day). I only switched off of Adderall XR originally because my doctor was concerned about the potential long term cardiovascular effects on my body."
