I brush my teeth after every meal - plus I drink between 100-120 ounces of water a day. I still get bad breath. I've order some chrorophyll capsules, and I will report back as to how they work. As far as the listerine pocketpacks, I am assuming no carbs = no sugar, since sugar always means carbs. Here is the text of the email they sent to me:
