In my experience, Seroquel "hunger" is a beast that can't be tamed. When I was taking it I could eat until I was stuffed and still want to eat more. I think it hijacks the body's hunger signals and just effs them up. Best of luck to you. Some people don't experience appetite increase on Seroquel, but I'm pretty sure they're few and far between. There are some on this forum who are lucky enough to be that way, but I'm not one of them.

Maybe eat a pile of veggies. Then do it again. And again.
