I switched to diet pepsi, no fat milk, light mayo, Turkey for sandwiches, no eating out, etc but I'm still gaining weight. I'm not getting off zyprexa, that's for sure. I can at least function for the first time in 4 yrs. Did God make zyprexa to make me fat? I really don't want to exercise either. And I have been. But I hate exercise. Is there anything to stop weight gain or at least slow it down? Please help.
