Seconding the NAC suggestion. I suffered from a bad nasal drip, lots of gagging. It's gone. Even if catch a cold I barely feel it, can still breath through my nose, clear lungs. If you have acess to NAC then getting seasonal allergies and colds basically becomes a choice. ​

gets harder every day for me to relate to people who still are worried about catching COVID. I have basically treated it as a myth for the past three years and have had no negative consequences. I've never lost my sense of smell. Hell, I don't even wash my hands that often unless they get sticky. Everyone got brainwashed into forgetting how a immune system works. Not nearly enough people understood the lesson of the Emperor's new clothes.
