Here is a link that should help. I haven't tried any of these but they look good.

Is there any sugar-free gum that doesn't have aspartame in it (see comment)?
This is the kind I chew :)
I really want to find minty sugar-free gum, but it seems like all I can find at the grocery store has aspartame in it, which I don't really like the idea of it. Does anyone know of any more "natural" gum or something? Any help is appreciated. :)
