Can I have some advice, First I was on Zyprexa, then Dr. put me on Latuda, then I asked for zyprexa back. I have gained 20lbs. Its awful, I wake up and eat in the middle of the night. Any advice?? None of my clothes fit, I want to stop taking it, and, do you think Lithium is contributing to this? I'm thinking of quitting all, I would rather be unstable.
