Bloating is fairly common...especially in the beginning of the cleanse. All the old gunk starts to hydrate and swell a bit. Also, any pathogenic bacteria or critters residing in the intestines may be dying off and contributing to the gas. You might want to do a parasite cleanse as well. I don't remember what the various herbs are in the Arise and Shine cleanse...they might be contributing to this. As the colon becomes cleaner the bloating should subside. Since digestion also involves the liver it would be a good idea to follow the Colon Cleanse with a series of liver flushes.
