Food Issues

I feel like I have a health problem. Every time I leave school and eat real food, my stomach rebels. A few days later, I get used to it, then go back to school, and have MORE stomach problems.

This makes me angry. I realize that Bon Apetit (our school's food supplier) probably uses fake food, which my body gets used to. The same thing happened to me when I got back from El Salvador, although it lasted for almost a month before they put me on the BRAT diet (Bananas, Rice, Applesauce, and Toast).

But I feel like this shouldn't be happening. Perhaps I should protest against GCC's food?

Has this ever happened to you?
