For me the easiest most effective Bowel Cleanse was doing Dr. Schulze 's Intestinal program. Super easy. You can find his info at the link below.
Part of it is almost like the psyllium and Bentonite stuff but has some other ingredients as well.
With his program, first you get everything moving (take his intestinal formula #1 in pill form - very easy and not time consumiong) and then do the formula #2 which really helps get all the old junk out and remove toxins. This is a bit more involves as you have to shake it up in water for 5 times a day for 5 days, but it is still easy. and Effective!
I did this and it changed my life! I felt a thousand times better and healthier. It was unbelievable! I had energy again!
