Flecainide
"I've been taking 50mg of flecainide twice a day for 2 years now and still love it. I have had  no incidences of afib and no side effects. I do like my alcohol and have 1-2 drinks daily. I believe the flecainide keeps me from having an alcohol related episode which my doctor believes is my trigger. I agree with him but also think dehydration, dieting and stress have been contributing factors as well, and again, the flecainide overrides them all. I'm sure it's not perfect for everyone, but for me it's been a godsend."
