I had OG covid just after Xmas 2020. Didn’t eat for 3-4 days, and was so excited for the first time I felt up to eating. That’s when I discovered I had no sense of smell. The basic tastes were there, salty, sweet, etc, but no nuance to it. With just the texture to go off, my basic white-bread-and-ham sandwich was like eating a wet sponge. It stayed that way for about 2 weeks, I think (the brain fog was real, too, don’t remember much of January 2021).
Started to come back slowly, and was normal by the end of March. Nothing much long term to report. Smell might be a little more sensitive now, if anything. We have cats, and I’m always the first to know when the box needs cleaning.
