In defense of montygram: people with health problems as severe as his are fortunate, and need a lot of courage and patience, to find a diet and surroundings that work for them. Once they find them, they usually tend to become extremely committed to them. But, their commonest mistake is to then assume that everyone wil benefit from them. Most of us won't.
So, montygram,be grateful, and accept my congratulations, but calm down a bit in this newsgroup!
