I've only tried the diet version, but I have to say I do like it, so that's another vote 'for'! Given the choice between that & diet coke with lemon I'd pick the one with lemon every time, though!
I know what you mean. The lemon "cuts" out some of the sweetness, the vanilla one is a bit synthetic-ey. But what the ****, the more diet drinks the merrier!!
I wonder if it was frozen would it taste like ice cream???
As you say, Peacock, it is so great to have another choice of diet drink. I get too bored with the usual stuff on the shelves.....
