I believe 90% of Dr. Clark's book is printed on this website. A lot of your questions will be answered by reading different posts on this website. I read a lot of Dr. Clark's book on this website and then ordered the book.
You will find everyone does their cleansing differently. There is an order in cleansing that Dr. Clark suggests , but you will find some people go right into the Liver Cleansing and skip the rest or will choose to do it later. As far as how often to do the liver cleanse, Dr. Clark will suggest every two weeks until you see no more stones. Sometimes, people do them a couple of days apart. A lot of it depends on your own health and how well your body will tolerate the cleanses. I remember reading one post from a man who did one and he seemed to think that was all he would need. Then I have read of people who have done more than a hundred!!!
Just read and read and read you will find all of your answers.
