Has anyone every tried a colon cleanser?

I may try Dr. Natura it’s a colon cleanser but I’m a little worried because of work. Has anyone ever tried one and went to work?

Start it Friday nite after work, and lighten up about Sunday afternoon. Getting rid of the body’s toxins is absolutely necessary to have a chance of healing from cancer.

You need to stay hydrated, with water that doesn’t have a bunch of chemicals in it, and you can use the herbal laxatives senna, cascara sagrada, and Turkish rhubarb root after you cleanse to stay regular. Best of luck.
