I was in a similar situation. I was on invega for three years and amazingly stable on that and emsam. Then I developed high prolactin, which led to a 70lb weight gain, which led to metabolic syndrome. Besides that, I began to have jaw clenching issues. So I had to go off of it. We tried latuda as monotherapy and that was an absolute disaster. Anxiety through the roof and hypomanic/mixed episode. So I called my pnurse and demanded something different. I'm am now on the combo seen in my signature. It was tough going from two meds to four, but it is what it is.

If you're not doing well on zyprexa and you've given it enough of a chance, call your doctor and let them know. You shouldn't have to suffer.
