I think I'd reconsider going back to work so soon, also the vacation, since you have a large hernia repair. 2 weeks is barely enough time for an easy fix, let alone one where thay'll be pulling your stomach back down and repairing the diaphragm. You'll still be on liquid diet after 2 weeks, maybe with added milk (full liquid) or soft diet if you are healing well. 2 weeks is about
time for the first checkup, when they might let you eat more, but not everything.
Mousy - These operations aren't guaranteed, and they don't last forever. So sorry you had a bad experience with your first one. I need a re-do also, am hoping they can do it lap.
I hope you will start your own thread and keep us up to date with your progress. They may be able to do the re-do laproscopically, or if not, maybe you can ask them to trim out the old scar and make it look better.
