How far should tubing go?

I would like to know if anyone out there can answer this question: I use a Fleet Bagenema which has a tube approximately 5 feet in length. If I'm able to cause the tubing to become pliable enough to move freely (use of fairy warm solution-at or above body temperature to soften tube, making it pliable) into my rectum, can I (safely) continue to insert the tubing into and past the sigmoid colon up into the descending colon, across the transverse colon and into the ascending colon? Or would that not be a wise/safe thing to attempt. I'm trying to reach as much of my large intestine as possible for a high cleansing. Are there rectal tubes made that are specifically made to go this far into the large intestine. Please help me with some information. Thanks. Tweet
