Next best thing to having a colon therapist.
In home colon therapy; I have used everything from enema bottles, to bags and fountains. This by far is the easiest, comfortable, and most effective method out side from going to a colon therapist and paying between $50-$100 per session.  The product is heavy duty and easy to clean. I have one at both of my houses and when I travel, I do have a fountain packed in my bag for relief while traveling. You could travel with a board after cutting it in half and put hinges on it, but that means an extra  bag to haul around.
