I've been on various PPI treatments since I had a motorcycle accident in my early 20's and ruptured my diaphragm.
I'm on Pantoprazole at the moment on an as needed basis. It comes and goes in severity but I know if indulge I'm going to pay the price which helps me keep it in check to a certain degree.
Man, that's an incredible difference in a year, a real achievement!
What I want to know though is how come you were in London and I didn't get to hear about it?
