What I have tried is the atkins shakes and stick them in the freezer until they are semi frozen, slushy like and throw them in your blender for a few seconds and then drink them, its like an ice cold milkshake. They also have the cafe au lait flavor drink. The other thing I have tried also is the same thing but with a bottle of crystal light and its like a fruit slushy..YUMMY I enjoyed these little treats.
