I have been on beta blockers since 1981 (160mg per day), and fortunately, they seem to be a good drug for my problems. I am also on Verapamil, a CCB, (200mg per day), plus digitalis.
I wish you the best of luck with natural meds! I do hope they give you relief from your problems! Let is know how they work for you... it would be nice to not be dependent on these silly chemicals. :)
