Brian, be sure and keep on top of your blood sugar levels. That's one downside of Manuka honey. You might consider trying 2 mg xylitol candy to see if it is the "coating" effect reducing the tongue pain. It could be as simple as some thrush areas which Manuka honey's antifungal properties would address. Xylitol has antimocrobial properties, won't raise blood sugar levels, coats the oral cavity almost like a gel, promotes more saliva production and is even being used as an energy booster. Most recent studies refute the cariestatic properties through remineralization, although the bacterial reduction has been shown to prevent or reduce cavities.

Remember the xylitol rule, "Strive for Five". Your goal should be 5 contacts per day of at least 2 mg. Somewhere around 15 mg - 20 mg has been shown to contribute to looser stools as well.
