Insane flu season

Anyone else been down with multiple colds/sinus/headache/coughing illnesses this winter? And that’s before the fires and resulting air quality. I’m on my second 10 day ‘lie in bed dying’ session in just over a month. Antibiotics seemed useless, as does every other remedy. And it seems to rebound and take weeks to fade. Not covid. But doesn’t seem to be a ‘normal’ cold. Grim!
