I picked up 3 Days to Vitality when I worked at Sam Weller's Books 100 years ago. Or was it 10 years ago I can't recall. I have since done this cleanse once per year and have used it a a tool to rest, reboot, and restore my system. It is a great intro to cleansing; packed full of great recipes, meditations, and info on additional cleansing tips such as screaming therapy and (ahem) enemas.
The only issue I have with this book is that it could be organized a little better. Some of the recipe page references within the chapters are off. I wish Pamela would release a schedule or planner to go along with it. In the meantime, I have created my own within an excell sheet complete with a shopping list and recipe schedule. Contact me if you would like a copy.
I highly recommend this book to anyone who is considering a juice cleanse and is looking for a place to start.
