Very helpful colon

What can I use to cleanse my colon?

Very helpful. I have just started a daily fiber regiment today using metamucil, and oatmeal. Apparently, I am supposed to be consuming appx. 30 grams of fiber/day. I am no where near that amount! for the past few months i have been experiencing what i believe to be IBS, where I have loose stool almost constantly. After a little research however, I am back on track.Thanks!
