How does the Master Cleanse work? Do I need to buy the ';book'; to do it?

I am interested in doing the master cleanse. What are the guidelines I have to follow? Any other tips...?How does the Master Cleanse work? Do I need to buy the ';book'; to do it?
Trust me I tried this and it can leave you in a terrible state. Its full of chemicals that can be harmful, especially to women. I would stay well away from it. I have since used an all natural body cleanse called the 21 day herbal cleanse and it works great. Try www.myhealthabcmall.com, its on there somewhere and you can use it up to four times a year to keep your system toxin free and healthy. I hope this helps.How does the Master Cleanse work?
