bipolar disorde
"I gained 10 lbs in under 1 week, which sets a speed record among the weight-gain meds I've taken.  Since that pushed me up to the pre-diabetic border, my psychiatrist pulled me off of it ASAP - not to mention that when you're severely depressed, how is super chunking up supposed to make you feel better no matter how well the med works?  1 month & I would have been up 40 lbs!  I felt no other side effects, nor any positive effects, but 1 week probably wasn't long enough for it to make a difference on my mood - only my rear end."
