Hi there. I was originally diagnosed as a paranoid Schizophrenic... diagnoses have multiplied and changed. Major one being schizoaffective disorder bipolar type. Anyway, I've taken I think all of the newer antipsychotics: risperdal, zyprexa, geodon, abilify, navane, I'm sure there's more but u understand. The one right now that's working for me is Trilafon. I totally relate to the gaining weight issue. I'm on 10 different drugs for various reasons; the bulk of which are psychiatric. But, I have actually lost some weight between 10-20 lbs in the past 3 months; which is a good thing bc now I can start to fit back into my clothes more. But, some of my meds have changed and my lifestyle has changed where I dont eat quite as much as I used to all the time; and I try to eat some fruit here and there. Anyway Good luck to you. You may PM me if u wish anytime
