Seroquel is a great med in my experience. It calms my racing thoughts, giving me a "mental break" if you will. It's also pretty sedating, and does a great job of putting you to sleep. It increases my appetite significantly, so watch out for weight gain. Then again, if you were on Zyprexa you've probably dealt with that type of side effect in one way or another.

I'm surprised it was that expensive for you. Did you get the brand name? I think it's generic at this point, so if they gave you the brand you might be able to get it cheaper as a generic. I'd call the pharmacy to consult.
