Anyone try this yet? They were giving out free 14 oz. bottles at work today, so I drank one. For the next two hours, I was literally about to jump out of my skin on a fantastic rocket ride to Jupiter. This stuff is not to be messed with. It contains something called "Power Pack", which I think is an amalgam of several ingredients found in "energy drinks". Anyway, you've been warned. Mountain Dew MDX is liquid crack.
