TweetOk....I feel a little wired, not much though...I guess considering they're $2.00 in bulk, paying what I did is not bad at all...The fact that I'm not as wired or that my body is taking it well, tells me that I have too much caffeine in my system...After reading up on all the stuff in it, I should feel much more than this after 2 cans of it....Either way, I like the drink, will probably buy it more often, just wish they would change the taste or get rid of the coloring....
