Thank you very much for your inputs - I suspect Gingernut has more than a passing knowledge about this stuff - but I like hearing it from the victims.
Lifestyle changes - good idea. I've kept up with the tea, coffee, wine and beer even while on PPIs but have decided to change. Problem is, I'm a veggie, eat a lot of fresh fruit and I note that some of the stuff that is good for veggies is not necessarily good for someone with reflux etc.
