I had those night sweats too when I came off of it. It will get better. I was on Lamictal as well while taking it and right after I quit Seroquel I went into a manic/mixed episode. I was high as a kite for 9 weeks...then I crashed into a depression. I have to say I preferred the manic episode to sleeping 14 hours a day and feeling like a blob. Things will get better, but I'm with blue on this one. You may need a temporary sleep aid. It will help your mood to stabilize more than anything. Sorry you are suffering.
