I agree, some/most medications have some noticeable side-effects. For example, Warfarin makes my bleed more freely if I get a cut or otherwise rupture a blood vessel. But, if I keep the level just right, I don't bruise for no reason, or have gums that bleed if I brush too hard, and I don't form clots, so no stroke, GREAT! I can live, even well, with the side effects and it keeps me alive and not a cripple.
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.
Beautiful dog, Jerry. I have the same kind myself and he makes my day, everyday. Nah, I don't want perfection, nor do I want to go back in time. I am a very lucky man.
