Multi Vitamin and Vagal AF

Can anyone recommend a good multi vitamin I can take along with the essential three, B12, D and D3, Complex B, and Theanine. Is there anything I shouldn't take? Have just been switched *from Sotalol and Eliquis *to Flecainide, Verapamil and Eliquis. I'm worried about the Flecainide as I stopped taking it when I read about the possible problem associated with it (I have mild CAD as well ad PD)however my Dr say it's safe ???? as I haven't had a heart attack (YET) Studies showed not good for those with heart disease.

I am still talking to my EP re ablation as I'm getting episode four to five times a month now and some of them are real doozies. He's getting frustrated because I cant make up my mind. Any thoughts on Ablation and Vagal AG, as I'm pretty sure mine is associated with my digestion and my vagal nerve. 95% events are night time after a meal, the others from over doing exercise or just don't know. Stress probably.

I think I am holding back o ablation because of my age more than anything else, but I do have those other conditions, Still working, still socially active etc.

Grateful for any input

What are the problems associated with Flecainide?
I'm on it and have felt short of breath since.
It has been shown that coronary disease can be reversed with diet (see Caldwell Esselstyn). There is lots of good information online and youtube.

Vagal AF responds very well to ablation. I'm a walking example myself.

The fear is natural (and rational).

Thanks...I have Parkinsons also so I'm unsure which way to go.

There is literature which says Flecainide should not be prescribed to people with blocked arteries, there was book written about it I recall called deadly medicine. Of course many of the drugs we take for AF are quite toxic.
