I had it. It was nasty. Fatigue, mental fog, and phantomsia (cigarette smoke in my case, lucky me...) persisted for months after. I also had abnormal heart rhythms and an increased frequency of ocular migraines (1-2 per year is "normal" for me, I had 4 in the 2 months immediately after getting over COVID and have had 2 since). Going into it, I was in extremely good physical condition. Coming out of it, it took me about 4 months of training to get back to baseline. I'm only now (~10 months later) back to where I was, in terms of my aerobic and anaerobic conditioning, speed, endurance, etc. FWIW, my strength didn't take much of a hit.
