I feel for you as I too gained many pounds on Zyprexa. Nothing seemed to help me lose. Now I have switched to Latuda and so far no more weight gain but it has only been a few weeks. Also I have had to take a few rescue doses of Zyprexa when I have bad insomnia and nothing else helped. I think it is like withdrawals from the Zyprexa.

It is difficult getting myself off it and maintaining stability. I really hope you find a way to do this soon as it is not something you want to live with.
