bipolar disorde
"I'm bipolar and this is the only medication (out of many, many) that really helps my bipolar and it works almost instantaneously for me.  I first went on it to gain weight because I was trying to recover from anorexia and struggling, but stayed on it for my bipolar.  I did gain weight and I eat tons, but I have a good metabolism and Zyprexa just brings me up to my medically ideal weight."
