narcolepsy
"I've had delayed sleep phase syndrome, mood disorder and ADHD all my life, due to brain injury at birth and a family pattern of delayed sleep phase syndrome. I managed a successful professional career but with great difficulty and with struggles with different medications. I way overused caffeine, with mixed results and side effects.  Provigil has been wonderful and I wish it had been available when I was a child and in school and working. I feel normal and alert and not constantly fighting sleepiness, inattention and depression. I can't help wondering how much better I might have done with this medicine. It is helping me with my second career as an artist.  "
