Karen...I mix the pre-mixed "Carb Solutions" with 1-2 parts Skim Milk, to 1 part shake. I LOVE IT! I can't begin to GAG it down straight,,tooo tooo sweet! It lasts longer when you mix it with milk, making it much more economical. I have found that WalMart carries it for 1/2 the price of grocery stores. Best of luck to you. Rhonda
