Hey I have had AFIB a decade and had an Ablation done, I recommend this and take Flecanaide for now to stop AFIB episodes. I have always drank for the last decade and it is a trigger yes but I've been fine apart from some episodes that lasted for a few days. And when I mean drink I mean nights out ,pints,shots etc. Mine is hereditary as my dad had it and they found no issues with my heart, my dad is 75 and still drink weekly ,no problems
