OK, yes, I know they're not exactly the most healthy thing on the planet, but there's times I really, really love a good energy drink! I like coffee, but when its 95 and muggy, these seem more refreshing,. and also, the B Vitimins and ones that have Ginseng give an added boost. I'd say my all time favorite is this one: Petey's Bing, Cherry Flavor, or Blackberry: (Have not tried the other ones yet) But I don't see this too many places, mainly my local Safeway...but really tasty, only 40 calories, and doesn't give jitters. But often, I find myself buying Rockstar, sugar free 'regular' half the time, and the plain 'ol sort the other half of the time, and having them over ice. Odd, but in the summer, I think I get a bit addicted : P But stick to one a day, generally.
