i have the same problem...haven't gotten to the daily vomiting, but had much trouble with eating and being able to do anything cuz of the incredible heartburn. i have been on aciphex for almost 4 years now and it works quite well at preventing much of the heartburn break throughs. tums takes care of it when i do happen to break through, so i can't really complain much anymore
as far as the mayo surgery, you sound like a perfect candidate. my dad had it done over 2 years ago and has loved it and the side effects of it. the basic procedure is that they take part of your stomach and wrap it around your esophogaus to hold your pyloric sphincter closed like it should be. the surgery is microscopic, so there is only 4 incisions across the bottom of your ribcage where they insert the scopes and lasers. recovery is quite long though....i think my dad was on bed rest for about 2 weeks and a month before he was able to do full days back at work. the side effects are quite good though....it shrinks your stomach, so you lose some weight which is probly never a bad thing, and it lets you eat almost anything you want...the only thing my dad still doesn't like is soda cuz the carbonation makes him feel funny.
he did have one bad side effect though, almost a year ago he woke up in the middle of the nite with terrible pain and we had to take him to the er and he was coughing and retching so hard that he pulled the wrap loose and ended up having to go through the surgery again. this time he came out of it much better and they found that he hadn't healed correctly fromt he first one, which caused the pain. since then, he has been great and having no problems at all.
feel free to pm me or email me if you have any specific questions that i can answer for ya
