the interaction with seroquel is psychological, complex, and not able to be answered not even a tiny bit without a detailed examination in person. but the stomach issue is really simple with alcohol. ALcohol is used to scrub and clean surfaces because it dissolves grease. This includes the protective layer and lining of the stomach. It not only causes ulcers, it increases acid secretion and reflux into the esophagus to make them worse. Interacts badly with aspirin and aspirin like drugs. Cannot say how bad a stomach lining problem is from the symptoms at all. Can be anywhere from normal to near fatal perforation with no symptoms to severe symptoms (yes, severe symptoms often have very little going on when scoped but I cannot say you do NOT have something really serious going on. Scoping. OR.. most commonly, modifying the risks and seeing if everything gets better in a week (no alcohol, proton pump inhibitor... if no more problem then no need to scope).
