obstructive sleep apnea/hypopnea syndrome
"This could be an important medicine for those who don't like taking medicines. I have chronic pain, and don't sleep well for a few days, then just coma-sleep because I am so exhausted by about the third day. When I am out driving, I don't like to take much more than ibuprofen until the evening, although the menu for me includes Vicodin, Dilaudid, Skelaxin, etc., as required. Have had 4 surgeries. My pain management doctor and I go round about pain medicines, and I know I wait too long to take it, but I think Nuvigil can be a great once in a while solution for when you wake up exhausted and have to be alert. I experienced no jitters or side effects, but was able to have a normal, productive day. No trouble sleeping and having some choice about my day. Priceless!"
