just finished 3 weeks and so far so good. Lost about 11 pounds and starting to get compliments. Tried WW in January and wasn't as successful as i am with this. Chocolate taste real good and I just ordered the vanilla. A bit on the pricey side, but it's the only thing that really makes me feel full so I'm sticking with it. Need to lose 30 pounds by summer. Maybe not a magic bullet but I'm happy with my results.
