Last night I had some Pepsi Edge for free when I swiped it from the cooler at my friend's work.
I expected the second coming of Pepsi One and Pepsi Blue, but I was pleasantly surprised. It's the true middleground between Diet & Regular, and for some reason it's great. It reminds me of a soda I used to drink a while ago. It also wired me the fuck up for a few minutes or so, which is weird since there's not as much sugar in it.
I'd still go with regular Pepsi over Edge, but for the people leeching to the low-carb shit, I think they'll enjoy it. However, all these Soda companies would save themselves so much money if they just repackaged their Diet brands as "no carb".
