Also near the beginning of 2020: I was sick AF for over a month with respiratory problems and fever and intense feelings of being unwell in ways I didn't know a person could experience. (Covid? Maybe. No way to tell, as far as I know. All I know is that I was in bad shape for a long time, that it came on very quickly, and that I tested negative for flu.)
Anyway, which b complex vitamin pills might you suggest? I'm game to try just about any low-impact way to turn down the noise.
