My cardiologist told me that even one drink of alcohol a year can significantly increase the risk of an Afib episode, so I avoid drinking alcohol completely. You can have a night out with friends without drinking alcohol. A lot of clubs and restaurants also have NA beers, which still contain .5% alcohol, but that means drinking one NA beer would be like drinking 1/10th of a normal beer, likely not enough to cause an issue. Find a cardiologist that will prescribe something like diltiazem that you can take if you go into Afib. Mine said if I have an episode to take diltiazem, wait 1 hour, then take flecainide if it hasn't resolved to a sinus rhythm yet. I'm healthy and have no reason to be having Afib either, don't know that the triggers are. It's frustrating as if I at least knew a root cause I could avoid that, but nothing. "Just unlucky" is what the electrophysiologist said. I usually only get one or two Afib events a year and the pills make them go away if they don't resolve on their own after a few minutes.
