For years I was a social drinker, occasional beer after work, cocktail with dinner out with friends. I loved an occasional "Jack Daniels Manhattan". I was advised by my Neuromuscular Specialist when diagnosed with MG, to refrain from any alcohol because of the effect on my muscles and coordination/balance problems. Well, I didn't listen and tried 1/2 of a beer with my wife one evening. Needless to say I will not drink again. The alcohol had a definite effect on my breathing. I'm not saying that this will happen to everyone, but please be careful with drinking alcohol everyone.
