I can't handle the side effects of loxapine anymore unfortunately.

My next pdoc appointment isn't until November 22nd (!), but I've been researching APs.
What one are you on? What AP did you or do you find the most beneficial?
I want something that DOESN'T cause weight gain, so no matter what I'm not going on Zyprexa. I also can't go on geodon or clozaril because of bad side effects I experienced.
I was wondering about abilify, saphris, latuda and Risperdal.
It has to have a generic or my insurance most likely won't cover it.
Worse comes to worse I'm just going to ask to go on Haldol again.
Thanks everyone.
