>>212599073 (OP)-the food is moving in the wrong direction and your body and your mind both know it but you can't help it, the food has to move in the wrong direction because something else is wrong, it's a symptom of something else that's bad
-tastes terrible and is extremely acidic and corrosive. Bulimics have serious problems with tooth decay because of all their vomiting
-you feel terrible because you almost always have other symptoms on top of the vomiting itself, you're nauseous because you ate something bad, you have the flu, you drank way too much, etc
-psychologically you know that you are at your absolute worst
-extremely gross, but also undignified and embarassing. You are expelling the waste into the toilet using your head, not your ass. Again, this is backwards and not what's normally supposed to happen
-you didn't even get to metabolize the food/water and turn it into energy/hydration, your body is literally convulsing nourishment out the wrong way to deal with a deeper problem or infection, so you're hungry and thirsty on top of being miserable
Hope that helps explain why vomiting is such a horrible experience! :)
