Glad your numbers are trending right. Watched closely myself, wearing a Garmin to track shifts. Used to be pretty muscular and lifted heavy, stopped once I got sick that December. Heart rate spikes easily though blood pressure stays fine, my heart compensating. Started a betablocker in May for that. Semaglutide came first, but insurance capped me at 1mg, pushing me elsewhere. No exercise plus the betablocker means metabolism's slowing, family history isn't pointing anywhere good either. Haven't told my doctor about switching GLP1s and raising the dose, dealing with that later. Heart rate is why I stick with tirz over reta, easier there. Hoping, like you, to slowly build tolerance as weight drops. Started around 123kg in April 2024, likely genetics, autoimmune issues, and other meds.
