I vomited at 6:30am this morning. I only ate bread rolls, ritz crackers, popcorn chicken, mashed potatoes, and corn today. It has all stayed down, and I am going back to school tomorrow, I am still worried about what I eat though. Should I bring a PB&J sandwich for lunch, or will that make me puke?

Depends on why you were sick, we throw up for dozens of reasons.? Where does popcorn chicken fit into a good food, if you can eat that, peanut butter should be nothing.
