I heard about this on a WW webboard, and I just had to try it for myself. You can buy it from their website,
http://www.sweetzfree.com.
It's pure sucralose in liquid form. I've used it so far to sweeten coffee and iced tea, and I've done some baking with it too, with great results. Very good for those of us trying to follow the IR diet.
Just had to share!
