Having this surgery would only make sense if it's medically necessary. It will NOT work for anxiety issues. David is absolutely right. The emetophobic's problem is anxiety, not vomiting. If you could never vomit again because you got this surgery you wouldn't necessarily be any more calm. For one thing, it's not 100% certain. So if your anxiety is bad enough, you will imagine that you are the one-in-a-million exception and that you will indeed vomit. Or else your anxiety would just manifest itself in something else. Whatever the second-most-scariest thing in the world is to you would become the first.

Spend your time, energy and money on treating your anxiety folks. Then you won't give a damn if you vomit or not!
