I brush my teeth twice a day and haven´t noticed any Sugar triggering, but it does help my breath for some time! my breath did get a little better these 2 past days :) and one day I accidentally swallowed a little bit. Oh well! Chewing gum does trigger your Sugar buds so you do have to be careful, I am very strict. It helps me to think that chewing gum during fasting for God means cheating and that helps me control myself, what sacrifice would there be?
Best of luck, thanks for reading and post your progress so we can all follow!
