I have been on Diltiazem and Metaprolol since 2014 when my Afib started. I agree with Dr. Joel Wallach that Afib is caused by nerves getting mashed with T-4 in your spine. I have been taking a long list of supplements for years. The side effect is no colds, flu or seasonal allergies. I exercise regularly and am a non-smoker. I do need to lose 70 lbs though. Six five at 275 lbs. The last weekby Kenai - AFIBBERS FORUM
