Terry. I am sorry that you felt so gross, but with a good fasting regime the things you have experienced would be nothing but good, since they are signs of the body throwing off the toxins that you have been accumulating. If you have a lack of proper knowledge about the way these things work it is understandable that you got scared.I have to knowledge of the schulze Bowel cleanse. Having done some serious reading on the subject I am more inclined to suggest you think seriously about visiting www.dr.clark.com/start.asp where you will find a good description of what you need to know. Good luck
