I buy the Toroni (think that's how you spell it) but others use the DaVinci. They are both flavored syrups made with liquid Splenda so they are carb free. There is a ton of flavors but not in my grocery store so I just get Irish Cream, Caramel, and Vanilla. Online there are other flavors like, chocolate, cherry, orange, and many more. You can get the DaVinci ones from Netrition.
