Just an FYI to all folks taking Seroquel....that high blood sugar thing is no joke. I had taken it for like 4 nights in a row and then tested on my friends blood sugar meter thing, and it was 151. I test at random because I am somewhat of a hypochondriac and the last thing I need is to become diabetic! My blood sugar had never been over like 90 w/o taking the seroquel. I am not taking it anymore, I would rather just not sleep or find a different drug (sucks because the seroquel works really good for sleep). I would say if you take it on a daily basis to buy a diabetic testing meter and keep track.
