I did earlier this Fall, and a few weeks ago I came down with something, that while not as bad as TBBF describes in their post, was still what I can only describe as a very bad cold, that lasted about two weeks. I was still able to work but was popping drugs multiple times a day to keep going. I did take an at home Covid test, which came up as negative, since it first started as a sore throat and that's how Covid started for me the two times I did have it. One person thought I might have the flu, but I never got an official diagnosis.
