MorningStar's link is hilarious! Everyone should read it for a good, cleansing laugh!
From a medical professional's un-biased viewpoint: please, please, please don't use any "detox" methods other than lots of water, fiber and clean-eating! The chemicals, supplements and agents in these detox pills and diets can cause severe derangements in your body's electrolytes and can cause very serious and even fatal reactions (including liver damage, kidney damage, bowel rupture, heart arrythmias and/or heart attacks, and more).
Usually, you will not see any problems...but do you want to be one of the rare few that do have complications? Do you want to take that risk? Is it worth it? (take my word for it....it isn't.)
