It's really just an individual thing. Earlier in my journey, I would drink an occasional glass of wine or cocktail (and EGGNOG during the holidays!) but I noticed it did magnify my symptoms, and nasal regurgitation of booze was way PAINFUL. I didn't drink at parties or publically much at all, as it was just too difficult, as I was unable to converse and drink. I also found that I did better if I drank on a full stomach...like a glass AFTER dinner--at home.
Now that my symptoms are well controlled, I can drink like a fish! Just kidding, but it doesn't bother me at all as far as MG goes.
Experiment and hopefully you'll be lucky and it won't bother you much! Good luck!
