Having been sugar free now for 5 weeks, feeling great and shed a few Kg's too. BUT, have a thirst that I would kill for, I didn't want to live on Diet Coke and proud to say, have only had about 10 small cans in this time. Thanks to my personal trainer, he has put me out of my misery by introducing me to Next Generation, Re-Fuel. Carb 3.5g per 100, sugars 0.6g. it does have sweetener's 954,952 (your call). Looking forward to using while working out.

Has anybody else discovered it?

I found that I very quickly went off all sweet drinks.  I'll drink diet coke in a pinch, but, I drink mineral water for a treat, normal water otherwise.  We had sushi in Sydney on the weekend, and they had a can that said 'water', I was told it was water, but it was lemonade.  I found it overpowering and horrible ( although I confess to eating some chocolate in Sydney, sweetened drinks are definitely way too sweet for me nowadays ).
