I bought 4 packs of the 1 serving Tropical. I was amazed that is was so good. I took it to work and used soy milk to mix with it. I felt full afterwards. It was my lunch and I had so much more energy afterwards. I honestly was not hungry the rest of the day. I work 12hr shifts as a CNA and I felt so much better after the Shakeology than I do when I eat a meal.
