@miki36- I haven't had COVID but I have had two Moderna vaccine shots. I've also had chemo, radiation and I have lung cancer. I have found that no matter what causes fatigue, especially very trying fatigue is to take it very easy at first. Your body has worn down from some sort of an insult. I found that the harder I pushed the more tired I became.

I had to pretend that I was starting at ground zero for getting back into shape after a serious illness. If I pushed too hard one day I took that next day off. I started with diet changes, better sleep habits, not allowing anyone near me if I felt stressed, including my husband. He even slept in the spare bedroom a number of times so that I could sleep more soundly. He snored very loudly, lol.

Your return to better health and less fatigue should be a smooth ride because you take it slowly.

Is there anything more specific that you are looking for?
