I take Vraylar and my insurance pays for it. I've been on it for 5 weeks and no weight gain. It's $1100+ for a 30 day supply of 3mg caps. My copay was $0. My doc also gives me samples.
Saphris was good for me with no weight gain on 5mg a day...but if you take a lot of Xyprexa you will need more Saphris than 5mg...probably 15mg which did put a little weight on.
Xyprexa for me put a ton of weight on me too. I couldn't function on 10mg. I just ate and slept.
Invega seemed to work but I took it with Depakote and Paxil so I gained a lot of weight but I'm not sure if Invega did it or not....I know Depakote does.
