Hummmmm. Throwing up. You can make yourself thow up, by eating too fast, too big of bites, etc, but it's not part of the plan/tool.
Making good food choices is all part of the training to use this wonderful tool to it's fullest. I hope your sisters poor choices won't get in the way of you choosing to be healthy.
I have yet to throw up. Don't ask about the other end!
