Are one of these "cleanses" the one you've been doing?  http://drclarkstore.com/colon-digestive-cleanse.html

The brief info you've offered indicated it might be this one (?) http://drclarkstore.com/dr-clark-colon-bowel-cleanse-standard.html

If so, I certainly understand why you're dealing with gas & "pellets" - as non-organic herbs stuffed into a capsule and isolated/fractionated supplements/chemicals (also encapsulized) is about as far from an effective colon cleanse as McDonalds is from "nutrition".  I'm sorry to hear you've wasted your money (and your time!)...and I doubt you've done any damage that can't be repaired (or won't repair itself).  There's no doubt, when it comes to "alternative medicine" (which is very much like allopathic medicine and virtually nothing like truly natural healing)...it's a jungle out there!  And most of the jungle is very harmful, ineffective misinformation (that keep us from learning the truth of natural healing) and toxic products that band-aid symptoms (which usually ends up causing even more symptoms in the long run).

By the way, virtually no adult on this planet is capable of cleaning & restoring their colon/GI tract in a mere 30 days.  Some people will see a few "ropes" rather quickly (and then see more after several weeks/months); others don't see them for weeks/months, and others never see them because the build-up comes off in pieces.  And hardly any one ever sees pieces or 'ropes' if they're not doing a full-spectrum colon cleanse like IF#1 & IF#2...along with the diet recommendations & naturally fermented foods (to restore gut flora), exercise, supporting herbs (if needed) and supporting therapies (enemas, coffee enemas, colonics, castor oil packs - whatever is needed).

Since bile from the liver is our natural 'laxative' (bile induces peristalsis), many people have very little success with colon cleansing until they start working on their liver (and get that bile flowing like it should be flowing).  Most everyone benefits from learning the information in this post: 'Separate Cleanses', Enemas, P&B, colon Q&A (buried post) (particularly the part after this line:  Doing one cleanse at a time, can many times work against us. )

If you haven't already, I strongly encourage you to read the 7 articles in the post (in the FAQ I previously linked you to) under this heading: Suggested Reading Before Asking Questions  This information is imperative for you in learning to be your own doctor.

Knowledge IS the key to healing & restoring our body (and the power & freedom we're all entitled to for living the rest of our life).

Healthiest of blessings!
