Whatever you do, DON'T go off your Zyprexa cold turkey. You're on a high dose and need to taper gradually with the knowledge and supervision of your prescriber. I don't know how long you've been on the Vitamin Z but if it's any longer than a few months you'll need to be careful. Please talk to your pdoc before you do anything. I know the weight gain is a pain in the @$$....and back....and feet....but then so is being in the hospital because you went off a heavy-duty medication without help. You are also on large doses of anti-depressants, and if those aren't decreased too you'll more than likely get very, very manic.

Best wishes for a successful weaning off Zyprexa. Have you asked your doctor about using one of the newer anti-psychotics, like Latuda or Saphris? These are supposedly weight neutral, as is the Geodon you're already taking.
