I used Provigil for fatigue, but found I was just hyper enough (in a good way of trying to overachieve) and like on a hyper kid, it had an adverse affect of bringing me down. Not being real hyper, made me really tired and found (as in many ADD+H kids (as they told me when older, making their own decisions and quit) clouded their brains. but remember every one is so different.) Have some had sucess with the Alzheimer Drug - Arrocept or something?
