Just did my first treatment. I bought a wag jag package of 3. I'm thinking I would have been better off saving my money. I would probably buy it if I had money to burn too but the price of a package of 9 or 12 (upwards of $1000) is completely not worth it if you're going to stress about the cost. I'll see how I do on three but my guess is very minimal loss. Save your money girls. You know how to lose weight.. just do it.
