My bro thinks I had the Rona

It's been two years since I got it, some things still don't taste right, Pepsi for example tastes like a weird chemically, bleach flavor anymore..but they did slowly come back here n there. I've noticed coffee smells and TASTES odd anymore too. Hope that it comes back to normal for you. I've heard people have to kinda "trick" their brain into it sometimes. I'm not sure why or how exactly..but it's worth investigating
