I just spent a few years trying to get the dosage right and proper drugs for my AF on top of HOCUM. By last summer I had lost body hair, libido, energy, stamina, muscle mass, and strength. Last fall I had had enough. I tapered off the Sotolol and cut down the Metoprolol. I still take the blood thinner,warfarin. I have re roofed my house, sheared 42 alpacas, regrown most of the lost body hair, and been able to work 43 hours a week with a 2 hour commute. I have less episodes of afib than when on the sotolol. I usually just stop what ever it was that triggered it and sit down for a while till it passes. The internist thought I had Apnea but it only showed up when they put all those uncomfortable monitors on me. I got rid of pillows and sleep on my side. Another benefit of less drugs is loss of 4 inches around waist and 5 lbs went away.
