bipolar disorde
"Only lasted 2 weeks at the lowest dose, stopped because the side effects were so intolerable.  Took in the evening, but still had trouble staying awake during the day, and felt like a total zombie when I did.  May have given this a couple more weeks to see if it would have worn off had I not gained 15 lbs. as well (with no appetite change - I wasn't awake long enough to eat more!). I was already 35lbs overweight from meds as it was, & when I med chunks me up, it doesn't stop.  
Only reason it gets 2 stars is that it kicked my chronic insomnia's butt."
