It appears to me that you may be carrying around a lot of waste matter in your colon, and while colonics may indeed be recommended, if you want immediate relief I'd suggest that you consider cleansing enemas at home to help empty your colon.
Start out by taking 3-4 pints of warm (103F at preparation) filtered or bottled water, and after eliminating, do a second enema to more fully empty your large intestine. You may have to repeat this daily for a week or so until you no longer get large amounts of waste matter in the return.
