I've developed food intolerances (or I always had them and didn't react as badly). I can't have wine, normal bread, pastries (I'd kill for a croissant), or any food with gluten. I'm currently not allowed beef, nuts, citrus and a couple of others.

I once ordered a focaccia with a bunch of stuff including artichokes. I was reading a gruesome novel at the time, whilst I was eating. So reading about body parts made me feel sick and I couldn't finish what I was eating. I've never been able to eat artichokes since.

I also don't eat sweetened condensed milk out of a can anymore. Ewww!
