This is weird. I wonder if people were coerced into answering a certain way. I have never had to make myself throw up because of alcohol. I would throw up if my body needed to and I hated throwing up. I guess I have thrown up at times when I felt sick and like I was going to throw up though. If people are drinking so much that they feel they have to make themselves throw up then they shouldn't be drinking that much in the first place. It seems obvious that they are trying to look cool or tough in front of their peers. If they are scared they've overdosed on alcohol then I guess it's good that they try to undo what they've done. I hope they learn from their mistakes though.
