Thanks for the posts everyone!!! I tried a full 200mg of the provigil on the first day, boy was I not tired, I was up til 1:30am!!! I did manage to get a whole bunch of house work done,lol. So the next day I only took half of that and seemed to do much better. I am hoping that I can get away with only using it as needed, maybe just because I am in a slump, it is more expensive than my other meds and really don't want another prescription to fill every month.
