If I am out and about all day, and desperately craving something that isn't water, but don't want to drink coffee or tea or a really sugary juice or pop, I'll grab a vitamin water.
There are a few that I like... The XXX one, which is acai and blueberry, or the defense (I think) with raspberry and apple.
I know they aren't great for me, but they are better than many other things I could choose, so... I probably have one every two weeks or so.
