I have been in love with vitamin water for a couple of years. I gave up southern sweet tea and cola for it. I was happy to see the 10 calorie make its debut but I am not really happy with the taste. It is sweeter and does have an aftertaste. I have actually tried to see what the "natural sweetner" is because it really reminds me of the aftertaste with splenda. Until they can perfect the taste to accompany the calories, I will stick with the original and not drink as much.
