I know that it's frustrating. I'm on a relatively low dose of zyprexa (and originally was on an even lower dose), and I've gained 30-40 lbs in half a year. I don't know exactly how much I've gained because I'm afraid to weigh myself! My jeans thankfully still fit, but they're starting to get tight. I've got to find a way to lose the weight while still on zyprexa because I am NOT going to waste money on buying larger pants.
