What food do you love but can't have?

I found out last year that I'm allergic to cashews. But I realized last night that I can't have marinara/pizza sauce too. I had pizza last night around 8pm, just one slice of cheese pizza. And I was up all 5am with severe heartburn. Nothing soothed me, I tried pepto, tums, and drank like a half gallon of chocolate milk. And here it is almost 24 hours since I ate the pizza and my stomach still hurts. I had pizza last week to and same thing. THIS SUCKS!!!! I CAN'T EAT PIZZA OR SPAGHETTI, my 2 fav foods.

Anyway what's your food?
