Hi- I get like that too only when I drink hard liqour....But I know its normal for hard alcohol to be harsh on the stomach but I don't think to the extent that it does for me...I have recently gotten blood in my stools after both huge stress situation, and after a night of drinking. I'm thinking ulcer and perhaps that was the first sign of it. Maybe you should cut back alcohol intake, or cut things like pop out of your daily diet. See if that helps.
