I am pretty much addicted to Diet Pepsi. I go through a case of the stuff in a week or a week and a half. Recently, I got the idea to add creme de menthe to it, and it tastes amazing. A slight hint of sweet mint really adds to the flavor, and it would make a wonderful "Limited Edition" Christmastime promotion. Y'all should really test market this, as I'm sure that once people get over the initial "why would they combine those flavors?" question and tried it, they'd love it.
