Good luck. It gets so confusing. I'm on metoprol also. I've given up weining off of it, cause I feel much better when on my dosage. There are annoying side effects such as low libido and little energy or interest in doing anything, this also goes along with the covid life style etc. I told my dear cardiology team at Scottsdale Mayo Clinic 3 years ago, that I didn't want an ablation since the idea of it scared me. Instead we did three cardioversions that didn't hold, they usually don't. Put on .....heart med who's name I've forgotten...that worked for about a year until Christmas and the holiday stress just slammed me out of rhythm and I gave it up. Then metoprol was recommended to slow the heart rate and see how I felt. By this time I was living in Carson City Nv and no longer a patient at the Mayo Clinic, though my cardiology said, if you need something major done, your going back to the Mayo, right? Decided then I'd keep it together with low salt and sugar, no caffaine (except alittle dark choc, I mean alittle). This helped. Also I study Christian Science and practiced affirmations of health and prayer, and this helped. Also received theraputic massage weekly, love this. Anyway, have improved alot. Maybe there is something better for me, but I'm exhausted by the process. At my lowest point 6/16, was in serious heart failure. Now just afib with leaky heart valves. I'm 73 and live with my husband, daughter and one granddaughter.
