Bipolar Disorde
"Took this drug for 6 months.  It did nothing for my mood, but it added inches to my waistline.  Worse, it made me scatterbrained as hell, kinda in a sneaky way as I slowly titrated, so that I didn&#039;t realize how bad it had affected my brain till I was off it, &amp; suddenly I wasn&#039;t a super ditz anymore."
