Narcolepsy
"I have only been on Provigil for a month, but it has caused extreme nausea and headaches. I have a history of cluster headaches and migraines, which had diminished, but are now back in full force. I&#039;ve also had stomach cancer twice and Provigil makes me very nauseous and losing weight due to an inability to eat. I&#039;m glad that it is effective for some, I just wish that I was in that group because I am TIRED."
