Diet Coke with Splenda Well, as you may or may not know, I'm a diet soda fiend. I've drank diet pop exclusively for the past 2 years. So Coke just came out with Diet Coke with Splenda, and let me tell you, it is fantastic. It tastes about ten times more like Coke than regular Diet Coke. It still has a diet aftertaste, but it's not near as bad as from regular Diet Coke. If you love, or just drink diet Coke on occasion, you have to go grab this. I just can't wait for the diet cherry and diet vanilla versions.
