You MUST take psyllium! And you must take the psyllium with the bentonite! And you MUST drink lots of water after the shakes! Otherwise you will clog yourself up worse than before! PLEASE, everyone go to cleanse.net! They are the first and foremost source of info on the psyllium and Bentonite shakes! You cant just drink the shakes!! Most people will just get constipated, like I did severely. You have to take something like the chomper they have on that site. It has cascara sagrada which stimulates the bowels. Cleansing will work much better! I got the book "Cleanse and Purify Thyself". I dont know what i'd do without that book. It tells all about it, how to use the stuff, what else to take, what to eat, and talks about problems along the way. Check ebay for the book, there's usually some cheap ones on there, ive seen as low as $1.25! You have to get more information on this type of cleanse before you start so you know what youre doing and you do it right. I hope this helps some of you with questions.
