In addition to the free book by Albert Mosseri mentioned in a previous post, there is one by natural hygienist Arnold Devries, Therapeutic Fasting, in pdf format, free.
It's good to go ahead and download or print these free books if you want to keep them because they frequently disappear from the Internet.
Here's the Devries book. Ive been reading all these during my fast to keep me occupied.
