red wine is what triggered my first episode of a-fib, it was the sulfites I do believe.
I have tried potato vodka (free of sulfites) the only other alcohol I know of that is sulfite free is tequila and I do love a good margarita!
Me tooo!!... A glass of wine does not bother me one way or another....but everyone is different.... you can try it and go from there.
Binge or or regular heavy drinking is unhealthy regardless of you heart condition.
To you question: I have a drink or two, maybe even three if it is an all evening event. I frequently have one beer or one glass of wine with dinner. So I say the above while engaging in light drinking while suffering from AFib.
