Mr. Pibb baby

But really I drink mostly "Zero" branded stuff. Tastes way better than the diet ones and I don't need the sugar. Coke Zero is way better than Diet Coke. Diet Pepsi is piss, so Pepsi Zero being drinkable is an improvement. I'll say I prefer Diet Dr. Pepper to Dr. Pepper Zero though. And for Mountain Dew neither Zero nor Diet is good.
