narcolepsy
"I'm in the navy and it was very hard fighting my sleep for the first 5 years of being in I finally got a sleep study an they diagnosed me with narcolepsy. I don't really like taking medication for anything but my doctor introduced me to Provigil. I finally feel like a normal person, although the first month I had very bad headaches it slowly went away and I went from taking 1 100mg pill a day to 2 100mg pills. My body got used to it within the first 2mths. Overall I love this medicine. works pretty good for me."
