Medication and Duration for Atrial Fibrillation

i’ve had proxies mother a fib since 2014. It would only happen during dehydration, post alcohol drinking, or after a big meal during the middle of the night. It became more frequent particularly during heavy exercise due to dehydration. I tried metoprolol but it did not work. Now I’ve tried flecainide with metoprolol and it seems to keep the a fib at bay as it had begun to happen more than just every few weeks. I was getting it every day on and off. The metoprolol extended release at 25 mg plus flecainide at 50 mg morning and night seems to help a lot in keeping the a fib at bay. It would still push through when the various triggers come into play but is now acting more like the paroxysmal a fib I’ve had for many years and has kept the daily a fib episodes away. I’m 58
