I've had some tinnitus for very long time (decades) -- usually, it was quiet enough to ignore and sometimes it seemed like it disappeared completely. It got way worse near the beginning of 2020. It became bad enough to hear all of the time. Even a rock concert doesn't really drown it out (yeah, I tend to wear earplugs for those -- but not quite at 100%).

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.
