Lemon is a natural diuretic so you don't need the MSM. In fact it takes a lot of water just to keep from dehydrating and use of MSM will increase your intake requirement (basic requirement is 1/2 your body weight in ounces).

OxyPowder does a great job of detaching old fecal matter from your colon walls. Just remember if you go that route you will also increase the chances of more difficult detox symptoms because as the matter is released toxins trapped in it are also released. As these toxins float through your blood stream you can end up feeling miserable. Again drink extra water to eleviate your detox.

I wanted to give you the cons to weigh against the pros of using such products.

Happy Cleansing,
