Acquired taste: Coffee, avocado, some hot spices (still mild by some of you asbestos mouths...), THC (Delta 8, specifically), most fish.
Given up: super sweet anything, cereal (the sugar and milk together WRECKS me), sour cream and talking smack. I learned from some savages in the Navy and after a bad incident, I had to give it up. Also, any pasta made in the US. Makes me and the wife really sick. Get the pasta from Italy? No problem...and we don't have to deal with that "gluten free" garbage pasta... ugh.
