Sorry if this is a repost?
Me being the bored unemployed self, I drove around looking for odd places to get food and drinks. I went into an asian market and found this gem
It tastes the same, but is not carbonated. and one small bottle of this has 125mg of caffeine where an 8.3 Oz of american red bull only has 80mgs, heres the best part, its only ONE dollar, atleast where I went it was. So if you love red bull but hate paying $2.19, check out local hole in the wall asian grocery stores.
