I have the breath problem and chew a half of a sugarless gum. Somewhere in the forum someone mentioned Trident makes a gum using Splenda. Have checked out my local stores and we only have Nutrasweet so far. It could be a Canadian gum or one just not in my demograph. I live very rural in New Hampshire. I have to drive at least an hour to get to stores of any size. I drink water and liquids all day. No one has told me I have bad breath, but I have this taste in my mouth. I know it is from lo carbing as before we fell off the wagon a couple of years ago, we experienced it then. So I guess that is some what of an indicator I doing a good job of lo carbing.
