Felicia, I'm one of those funny ducks who can gain weight on lc chewing gum. It's not the sugar in it, but the chewing action pouring out saliva and other enzymes. Seems to whet my appetite somehow. I think part of the reason we ended up so big is our need for oral gratification. Keeping anything in our mouth for long periods does not help retrain our bad habits; what happens when we are accustomed to a wad/lozenge/etc always being there, then we run out? Think about it.
