Have you tried the drink that they sell called Tru Blood? I hear it's pretty good.
Some friends of mine made me try it (peer pressure, aaaaa!) and it was odd, but in a way I found pleasant. Sort of like really tangy liquid sweettarts -- I don't know if there are different variants of Tru Blood or not, this one was in a bottle, and the color was... disturbing. I did actually hesitate before the first sip, a little terrified that it would be thick and coppery. Blegh! (It wasn't, so yay!) If you like the tast eof most energy drinks, you'd probably like it. If not, keep the bottle sealed, and it's an interesting paperweight or something.
