To my understanding, no way you can get water to your small intestine doing enema. I suggest if you bother to do enema do coffee enema. just 2 cups of coffee will do the detox. Here is a link perfect for your coffee enema needs. The coffee enema kit comes with dewormer, coffee, castor oil pack and reusable enema bucket with tubing.
Good luck. http://www.lakechkebede.com/store/order-here-complete-coffee-enema-kit/
