I had highly symptomatic paroxysmal afib with extremely high heart rates (>180 bpm) from 2002 to 2017, dealt with 3 different EPs, tried almost every antiarrhythmic drug there is, and not once did any of those doctors so much as mention amiodarone. I mentioned it once to one of the doctors and he just shook his head and said, "I would never put you on amiodarone."
My opinion: A resounding NO to amiodarone. It should be the drug of last resort, not the first choice.
But more importantly, when you're in afib, how do you feel? Does it have a big impact on your quality of life? Does it limit your activities? Does it make you feel dizzy or faint?
If you answered no to all those questions, then I question why you need to do anything at all. What you're doing now is appropriate and sufficient to prevent all the bad stuff afib can cause. If you do experience severe symptoms, there are other, safer drugs you can try first.
