ive drank so much red bull and rockstar that it takes me at least 2 to get going... and i can only drink so much espressos in one day
but a good friend of mine who probably wants me to die of a heart attack, introduced me to this...
tastes kind of funny, but its the strength of 3.5 redbulls. Only sold in limited places, but they have a list on their site.
