"after a few days on nuvigil (after experiencing provigil) i found it to be excellent for my adhd.  provigil made me feel anxious all day to the point i could not run or workout in comfort.  the first day on nuvigil was the only day i had this feeling.  

the side effects for me are dry mouth and suppressed appetite.  it is so nice to be focused.  the worst effect was muscle weakness! i went from running 7 miles to not being about to run more then 7 minutes. "
