Personally - I am not a fan of colonics. Some may not agree, but when you go out of your home to have someone else do this for you, I feel uncomfortable about the possibility of less than perfect sanitary conditions. It sounds like you got good results with the Oxypowder , and if you have occasional constipation, you can do a brief Oxypowder "tune-up", or take some Oxypowder s for a couple of nights. For me, the oxy-powder combined with home enemas as needed when I'm detoxing works great.
After doing a liver cleanse, it's important to do enemas or even the home colonics with a colema board. To me it seems like more of a hassle to have to go to someone else to do it when you can get adequate results at home. It also has some risks, however slight that I'd rather not deal with. Not to mention that it costs a lot more.
