Need sugar-free gum or candy suggestions

I have a desk job and I constantly want gum/candy, etc. I am trying to overcome my sugar/sweet addiction. I can't eat a lot of the sugar free products due to the tummy side effects. I like Spry gum (Xylitol), but it gets a little pricey. I do keep liquids handy, but I still need something else. Any suggestions would be appreciated.
