I understand your frustration. Long Covid gave me A=fib, I take a cocktail of meds which includes a stool softener because the meds cause constapation. It could be whatever medicine you have to take and not a physiological change. I also eat 5 to 6 servings of fruit daily up from 4 daily and a tablespoon of oat bran morning and night. I also take 600 mg of mixed magnesium, which has been a routine for at least 30 years.

I'm managing OK overall. But, I want the life back that I had 8 1/2 months ago i.e. pre-covid!
