It’s not all just negative tbh. I suffered from it myself and was an strict pescetarian before as I couldn’t stand the taste of any meat besides fish.

Caught Covid and suddenly milk tastes like caramel and I started to enjoy the taste of beef and lamb. Coffee smells weird though, it triggers the same response in my brain as “A dog just pooped in the house two rooms over”.

That last one is what annoys me. My sense of smell never relearned to distinguish those two things.
