Good on you for doing the colon cleanse; I'm sure it will help you alot! I have done about 12 colon irrigation sessions, and I have done Oxypowder as well; and me thinks I have had poo breath too; but noone is game enough to tell me. After years of taking medications, my colon was very backed up and jam packed full of poo. Anyway, both are great methods for cleaning you out and stopping you from bringing the poo up the wrong way!!! (i.e., up through the mouth). The Oxypowder is quick, cheap and really works, if you don't want to do anything involving going to a clinic. You may also want to think about taking a good probitic, and also flossing/rinsing before brushing as brushing may just abrase the bacteria back into your gums and into your blood stream.
