I think some regular coke drinkers will switch, but I won't be one of them. Like WB says it tastes ALMOST like the real thing, but you can tell it's not.
It is similar to mixing half classic and half diet at 7-11. You can still taste that aftertaste. Maybe my taste buds are very sensitive. Too bad for me. I'll have to stick to the 9 teaspoons of sugar and colored carbonated water.
