When you need that extra kick...
This is perfect for me for the times that I get that low-energy feeling.  It's 4 calories, about 5 sips, and the Pomegranate is actually pretty good.  The Berry isn't bad either.  Amazon Marketplace has a great price on this product - much better than in a grocery store.  My brother has been using it for years and works very well for him too.
