I developed an allergy to chocolate in my teens. The first thing that made me sick was Jr. Mints. So just the thought of mint chocolate instantly makes my stomach hurt!
The allergy didn’t last, and about ten years later I was able to eat chocolate again. Though I do seem to still have an intolerance to it (an intolerance is when you simply have to go to the bathroom. No hives or anything) if I eat more than a few ounces in a week. So I don’t usually have chocolate around, and don’t choose it all the time.
As a small child, I didn’t even like chocolate.

Funny, huh?
