bowel preparation
"I followed the instructions on the product.  My Gastro suggested that I take four other laxatives, two days before my procedure and two the night before, followed by the Prepopik prep.  I drank twice the recommended water and still I had a 'dirty' colon.  I knew, even before the procedure that I wasn't clean and informed the doctor.  He told me  that I was right... If I knew it before he did, this is not the stuff for me!!"
