Chocolate makes me sick. It doesn't depend what it is: candy, deserts, milk... if it's chocolate, it will make my stomach hurt. White chocolate is the only type that seems to be a little easier on my stomach.
Also peanut butter. I don't like the taste of peanut butter anyways, but everytime I eat it I get a headache and my stomach hurts.
I get car sick really easy too. I always have to sit in the front seat of a car, because for some reason that helps me. I get really sick in the backseat
