I'm a newbie and I've read lots and lots online but not the book so I'm hoping someone will indulge me: I read that the book does not recommend the Master-Cleanse for anyone who does not have 1 BM/day. Why is that? I'm trying to assess: sometimes I'll have 2, sometimes none. I feel that I'm in pretty good health. I'd like to know more so I can see if I should apply that to myself.
