I don’t know what dose you’re on. However, I found that I’ve only put on weight when I’ve been extremely unwell and my dose has been ramped up. Once I’ve recovered from an episode my Seroquel dose is lowered back down and my weight drops back down.
I’ve been on Seroquel for 4 years. I take both the extended release and the immediate release. If it weren’t for Seroquel I’d be even more unwell than I am.
