Narcolepsy
"A doctor in the ER prescribed me 200 mg of Provigil when I was first diagnosed with Narcolepsy. It didn&#039;t seem to have any effect on me at all. Then I went to see my sleep doctor and he prescribed me 250 mg of Nuvigil. It finally allowed me to stay awake for an entire day. But if I went out somewhere I would be able to come home and take a nap and be fully awake again. Taking that with Xyrem makes me feel 98%..not quite 100, but still pretty great."
