Uncomfortably Expensive
This is the first carbonated drink I've seen with warning labels, and I wondered if I should just drink 2 cups of coffee instead.  However, I received these on the agreement that I would try them out and review.  The taste is odd, and was a bit unpleasant to me.  They certainly made it taste sweet for being sugar free, almost to excess.  My son tried it and thought it was OK.  I don't think either of us felt any energy gain, but we both had mild paranoia wondering about side effects.  I was stunned by how expensive these are (at least at the time of this review).  I'll stick with coffee and save money and not worry about health warning labels.
