My vomiting experiences have all been quite tame. When I was 7 or 8 I had mumps and my mum could only get aspirin crushed in milk down me. We went to my aunties and she managed to tempt me with some blackcurrant cordial. When we got home I puked it all over the bathroom floor. I HATE puking so was really quite traumatised by it. To this day I don't like like having purple foods/drinks and my first thought is always, 'what if I puke it up?'
I think popcorn woud be the worst thing to throw up.
