I'm also on seroquel XL... my regularly prescribed dose is 350, though it recently went up to 450 after I had an episode. I'm now titrating back down again, and am actually wondering if I can come off this med, since I'm really feeling normal again. Won't do it without my doctor's say so though... I've seen too many disasters from medical non compliance.

I can tell you that the extreme hangover will wear off. I was told that if I had bad somnolence in the morning to take it up to twelve hours before you have to get up. That seems to help. But I'm afraid it will take a couple of weeks before the wooziness disipates. Hang on in there.
