If my next ablation for persistent AFlutter fails, I expect to return to my Tesco Guatemala strength 4. If it works I will stay with my Caffè Nero decaff 12 second macchiato with an extra shot - surprisingly good.
I hope to hear whether members with persistent/permanent AF either continue to, or have reverted to, normal coffee and enjoy the odd single malt. Or does it make your PermAF more symptomatic?
Behaving normally in that regard, would be one of the upsides of failure, amongst many others I suspect.
