Looks good TK,
There are a few people that have some issues with aspertame. You can search the web on "phenylketonurics" to see what kind of issues some people may have.
I'm a bit of a purist and would suggest to anyone, that it's best to get in the habit of good ole H2O (nothing better than nature's nector), but since this has 0 calories, it should be ok.
You'll be surprised how habit forming water can become, once you get used to it....
Happy Shakin',
