narcolepsy
"I've been on Nuvigil for about 5 weeks for narcolepsy. I can actually function. I was prescribed the 150mg 1x/day and initially had very bad headaches for the first week or so and was taking ibuprofen to deal with them. My doctor had me cut the pills to take half when I wake and half 3 hrs later and I no longer had the headaches but still had the wakefulness. I do occasionally experience severe dry mouth that no amount of water can fix, but no longer have headaches or any other problems, and am actually awake. I do get urges to nap, on occasion, but they are resistible. Amazing to be able to be AWAKE again!"
