Back on track for a minute Al, do you find you get this acid feeling an hour or two after eating? Just another thought but ask your doc to check you for Helicobactor Pylori bacteria in your stomach as these can cause ulcers in the stomach wall.

Poacher turned game-keeper
Hope you get it sorted soon mate!
Interesting that it doesn't affect you after a ride on the bike?
PS - How is the beast?!
