narcolepsy
"After looking over the sleep study results my Doctor concluded I have narcolepsy. He has put me on Nuvigil (1x-150mg). I will say, the first 2-3 days felt great. After that, it went and still continues to go down hill. I feel tired and am weak, but my eyes aren't closing like they used to. I kind of wish I would just fall asleep. I have this extreme dull headache that won't subside and dry mouth. I meet with the Doctor next week, hopefully we can change things up."
