Awww, you guys are so sweet. Thank you for all your kind words =).
ACV is apple cider vinegar and I only mean the kind with the mother in it. From my understanding, there is no harm in ACV enemas. The only negative thing is because it is so cleansing, if you use too much at first (more than 2tbl/1qt) you could experience painful cramping.
I also do Yoga and I've found the breathing techniques learned are quite useful when doing enemas. I don't know if the breathing you're talking about would equate to a colonic...I guess it depends how much you actually get the water to move around but a good place to ask is www.healthandyoga.com they also sell enema setups for $30.00 which is where I got mine and it is very simple and easy to use and clean.
