I've read about some people who have no trouble vomiting after the procedure. Personally, I had the fundo 6 months ago and I cannot vomit.
The procedures wraps your stomach around your esophagus, creating a new barrier when the LES doesn't work correctly. This works because every time the stomach contracts, it tightens around the esophagus, thus keeping food and acid from coming up.
While it isn't pleasant not being able to vomit, that side effect has far outweighed the symptoms I was having pre-surgery.
Other things to think about before choosing surgery:
You should never gain weight past what you weighed when you had the surgery because you could put stress on your stitches.
You will need to really chew your food. If you swallow someting too large, you run the risk of having it get "stuck" above the wrap.
