MC…thanks for the suggestion, I will check out Ice Cubes. I have found a xylitol-only green tea flavored gum called Spry by Xlear, Inc. at a local health food store. So far, so good. Waiting to hear from company if there is any caffeine from the green tea. Even if there is, I should not think there would be enough to stimulate reflux? My only concern with xylitol is that Norm suggests no sugar alcohols?
Also checking on a gum called Xylident, which is xylitol with the bicarbonate. No one sells it locally, but health food store may be able to order it.
