My personal beverage choice is diet Pepsi. I probably drank Coke when I was a kid and remember actually taking the Pepsi Challenge. I actually chose Pepsi. And then about 23 years ago or so (somewhere around 1990), I started drinking Diet Rite (the diet version of RC Cola) and liked it. Then I discovered diet Pepsi and never looked back. It's DP for me. Diet Coke from a fountain is an acceptable alternative, but I really don't care for diet Coke in aluminum cans. I just don't like regular (non-diet) colas of any kind anymore. Regular root beer, orange soda, things like that are okay, but not cola.
