Colon Cleanser

Last few months i purchased the (i thought) best colon cleanser at store because of the fact that i want to get rid of all the junk foods in my system. I felt good when i was on that program. It helped me lose weight and plus, my problem on using the bathroom was resolved. Now, i plan on going back the program but thinking the 30dollars for each bottle is making me on doubt. Overall, i love colon cleanser but i sure want to find one that is less expensive and at the same time effective product.
