Seroquel is a tranquilizer so mixing that with alcohol is almost guaranteeing a black out or some other harsh incapacitation. Also, I am not sure what you mean by "HAVE to get fat on my seroquel"
I was on seroquel for 6 months. Gained 35 pounds, still haven't lost it all. If you take seroquel, probably for bipolar disorder or schizo, you shouldn't be bing drinking to "oblivion" at all.
