Your sleep doc prescribed you provigal because its mainly for narcolepsy, but for any other meds really youll probably have to go to pdoc. There is a lot of meds for add/adhd. Ive personally tried 5 hah. I liked provigal but youre right, they are basically super expensive caffeine pills. I take adderral which is amazing at helping me focus and concentrate but they can have many side affects, ive been lucky enough to get practically every single one. Cant tell you about any others because they all made me sick.
