I've been on Thorazine since September and my psych. wanted to increase it, which I was against. I'm scared of the side effects of Thorazine. He's switching me to Zyprexa, so that I can be on a bigger, safer dose, but he says some people can gain upwards of 50 pounds!! I've been thin all my life and I don't need weight problems to add to my worries.

Can Zyprexa users please enlighten me?
