Thanks all of you for the feedback. It's much appreciated. One main lesson I'm taking is that Seroquel does dramatic things to the body, and some of those things are to be worried about.
I didn't realize 50 mg was so small a dose, compared to how Seroquel is often ordered. That makes me a bit less anxious that it's going to do something awful to me.
I'll be glad of hearing from anyone else who's used this med.
