I read this book and began drinking green smoothies every morning before I even finished it. I immediately fell in love with the taste and the feeling. Never a morning person, I now wake up every morning between 6-7am WITHOUT an alarm! These results are from simply drinking one in the morning (some people drink more) that is about 32oz. (2 big handfuls of spinach, kale, or purslane; 2 cups filtered water; a piece of fruit or veggies). I highly recommend this book and its teachings!
