To freshen up their breath, most of my friends pop a Tic Tac a piece of gum. I also know a few who carry around Icebreakers, but I've never tasted a mint that had the refreshing power that Altoids do. I have a box of Altoids on me literally all of the time. No other mint does it for me. What do you like to pop in your mouth when you need to feel fresher?
