I'm at 4 years (March 2020)
I still have long Covid. Symptoms continually evolve.
I am better off than I was.

Symptoms that remain:
1) tinnitus
2) diarrhea
3) dizzy spells, although far fewer in number, no less severe when they do happen.

Fatigue largely gone, although I do get tired too quickly, if and when I do exersize. Insomnia mostly gone. Rashes long gone (that was beginning only).

Taste and smell might still be a symptom. But now it's swinging the other way. I now taste and smell more acutely. Better (or more intensely) than 30 years ago. This has to be a neurological response. First one way and then the other.
