what you might be doing for a colon cleanse? Water is the best thing, unless you are going for a colonoscopy. Then there is over the counter super cleaners and boy, do not get more than 5 feet from a bathroom. When it works, it works.
Here is a great article on colon cleanses. It really needs to be something super gentle.
