I have some side effects
too from Beta Blockers, but these too are minor
, unless I feel I have go get back to long distance running (a past exercise) or other hard physical work. Would I like to be able to do those things again, yes, but I'm happy to live without them if my condition and medication side-effects make it necessary.
Would I like to see a perfect fix, make my heart work like I was 20, or even 50 YO again,, yep, but that hasn't happened yet to my knowledge.
