HI MICHAEL,
Your right about what you hear, ive had numerous colonoscope examinationations. The day before the test you dont eat nothing only drink fluids. Then that evening you have to take a prescribed laxatives to clean out the loarge intestine and a few enemas. Now from what ive observrd from taking the prep for the test there is no such build up of anything in your system. These people are comming up with these cleansing remedies to sell to the general public just to get theri money because so many people are preocupied with their bowels and their movements that they spend millions of dollars each year buying over the counter laxatives.
