@badastro Very sorry to hear that. I was one of those that got it already in March 2020 (frequent flier ... ) and then once again later in 2021 (small kids in school). It's "like a cold" if you've had it a bunch of times, not if you're a first-timer! But be glad for that "mostly one day" rather than a full week! :)
"a headache that Tylenol couldn’t touch"
Paracetamol sucks as a pain reliever - it's only really good for bringing down fevers. Always Ibuprofene :)
(Petrov mentions it in this video but I think he points to another that goes into more detail. RFK Jr:s idiotic claims aside, Paracetamol is a really crappy medication all in all: https://www.youtube.com/watch?v=4mIZykAItBM )
