When i told my GP that fatigue was getting to the point where i could not get out of bed in the morning, he prescribed provigil. For me anyway, it never did anything more than a couple of cups of strong coffee! I could take it and go to bed and sleep!
I dunno, but i think that provigil holds no current special status as a new drug for any applications that older drugs don't fit. Sure , it is chemically unique as far as a structure of a central nervous system stimulant, but I don't think it's anything better than what we have on the market now, that is, generic and cheap. cs
