I was on 25 mg of Haldol awhile ago. I am talking about the pills, not injections. It made me sleep 20 hours a day. Right now the one I'm on is not responsible for the weight gain, but its Latuda. Was on Risperdal a LONG time ago. I mean years. I've been on nearly every anti psychotic except a few and I refuse taking the ones like Zyprexa and Clozaril.
