So yesterday I used some Cool Mint Listerine mouth wash. I then ate a piece of Wrigley’s Winterfresh gum immediately afterwards. It was the most unsatisfying piece of gum I’ve ever eaten. All of the flavor of the gum was completely masked by the lingering after effects of the Listerine. By the time the Listerine wore off, the gum had lost all flavor and sugar. Yum.
