Hi pixy_nixy,

The dreaded aspatame is one reason. Also there is a body of opinion which thinks yopu should educate your body away from sweet things. Other people think that the artificial sweeteners trigger an insulin release like sugar. If it is of the diet coke type there is also the caffine to think about.

Personally, I think it's up to you. If you can drink it and lose weight, good for you. if you give it up, or cut down and drink water instead better for you!

Good luck,

Robert.

P.S. I drink it - but I'm stuck at the moment so I'm not a good role model!
