depression
"I have used Provigil and now am on Nuvigil that helps for various issues. I realized I may have an attention problem when I took Provigil for the first time and scored 10-30 points higher than I ever have on a Vocational Rehab. IQ test. 

For those of you who are low income, there is a foundation called Cephalon Cares that gives me my medication for free. You have to be under a certain income level but it saves me much money since I do not have insurance either."
