Alcohol does cause decreased transmission of acetylcholine, like Abby said. It also has sedating effects. And you may not know right after you drink that wine how your MG will react. Hours later, when you're sleeping, you may wake up choking, unable to breathe for a few seconds or more. You might not but it's not a pleasant experience. If I have even a teaspoon of champagne, I will have that reaction.

If you're going to test how your MG reacts to alcohol, you might want to do it early in the day. And since you aren't doing well right now, it might be a good idea to wait until you are! Pushing that envelope is not the best idea.
