I don't tend to feel disgusting after eating. The only occasions that I can recall would have to either be those nachos that I simply at far too much of (about 5 pounds of nachos, heaped in a pile on a huge plate), or the one time I made a sandwich out of bread, peanut butter, bananas, candy corn, and egg salad.
I at the whole thing, then I regretted it. Didn't vomit or anything, but my stomach certainly wasn't pleased with me.
