I'm recommending Dr Vivian Vetrano's latest e-book, "GETTING WELL THE EASY WAY!"
http://www.amazon.com/GETTING-Important-Necessary-Recovery-ebook/dp/B008R08W0...



Dr Vetrano does an excellent job, in my layman's opinion, of explaining why rest and sleep are such an important part of fasting or just healing in general. I highly recommend this book to everyone regardless of your healing/fasting experience. It only costs a few dollars and it's money well spent for the information provided.
