CoCo, I have read volumns on fasting and do it for the cleansing benefits, my wife just watches and shakes her head but it is amazing when you study and research on the benefits and how to do it. I don't do all the colon cleansing stuff, but do drink Senna Tea, may sure you are close to the toilet and don't leave the house, but I usually dont eat bad for the most part either. When you get past the first 24-36 hours it becomes fairly easy, the hunger pains stop and then you start to release the toxins and drink plenty of water to flush them out.
I typically drop about 7-9 pounds in just 3 days of water then veggies and fruit for a day before I get back into eating normal. Good training of mind and body on self control.
