The Nissen Fundoplication surgery is the gold standard for stopping reflux. Everyone is different, but I can tell you that I went on vacation after four months, and enjoyed eating out a restaurants. I was back to normal as far as eating went...I could eat and enjoy anything I chose. You'll always have to chew more carefully, but if your recovery was anything like mine, you shouldn't have a problem on your cruise in April.
Good luck with your decision! If you decide on the surgery, be sure to take the time to research which surgeon you choose. You need to find an outstanding surgeon with lots of experience doing Nissens (at the very least, 300 procedure). Be sure to ask lots of questions. You'll need to have several tests--barium swallow, manometry, endoscopy, and 24 hr. PH monitor.
I'm glad you've joined us! Be sure to ask absolutely any questions you have!
