I would say not having enough protein on your stomach is probably what caused the upset. Sugar is one of those things that can cause discomfort for gastroparesis, so the combo of that and the alcohol is probably what pushed it over the edge. I do best if I have eaten a full meal or have had something high in protein and sodium before I drink. I typically can’t do more than 3 drinks before my stomach starts trying to spasm, so just pay attention to what your body is telling you and go from there. Best of luck!

Are you prescribed Reglan yet ?

I would recommend cutting out the gluten. As it starts to digest, gluten looks like foreign DNA. With an autoimmune disease (like gastroparesis) your body sees foreign DNA and overreacts to the extreme.
