Ian,
I know you have good intentions but I just don't buy into surgery as a miracle cure. There's just too many possible side effects for me to risk at this time. A good exmaple...if nissen is so great why did they come up with linx, TIF, LES pace maker? None of them are full proof, if they were I'd wouldn't hesitate.
My day under the knife may not be that far off but I'm not there yet. You have said your going forward with surgery, which one appeals to you?
Most of the time when I bet on sports, I win (it's something I'm good at and understand), however when I go to the slot machine, I walk away broke. For now I'll pass on the game of roulette.
I wish you all the best and success with your surgery.
