I didn't get it until late December 2022, that I know of, but I was the sickest I remember being in Nov 2019 and I have got to wonder if I had it back then. In December, it kind of manifested differently for everyone. We all got sick, but I think I got it first. Ironically, what made me wonder later on was that I had these aches like even my SKIN hurt, and the only thing that had made me feel that way before was the COVID vaccine. Hmmmm. Son spiked a mild fever for a couple of days, had a slightly runny nose, and got over it like it was nothing. I had bad chills in the middle of the night (like real bad, thought I was going to break bones from shivering) but the main suck of it was a cough, then laryngitis, that lasted for weeks. My wife had ear pain, and never had as much of a cough as I did, but she was misdiagnosed at first and given a corticosteroid for her ear, which made her worse, then we later found out she had COVID when she lost her sense of taste and smell and we tested. I never lost those. Hers came back in like... a couple of weeks?
The main thing that I did was alternate Sudafed and tessalon perles for the cough, every other night. No particular reason why, that's just what I did. That and lots of hot water with honey and lemon, hydrating, avoiding dairy (mucus), and sleeping as often as I could/felt the need. Do what you need to do to get as solid a night's sleep as you can. That will help the most. And yeah, as others have said, don't zoom back to normal life as soon as you feel better. The fatigue that comes with COVID is pretty sneaky. You may think you're well, but you aren't, and you will wipe yourself out pretty fast.
