In a water fast, tea and salt water flushes are contraindicated. That much i do know.
As to water enemas, i really believe they help me, but chrisb1 believes you are better off without them. So with respect for his words i would say you could go either way depending upon your preference. If you should do them, distilled water is highly recommended to protect your healthy intestinal flora (bacteria) from the chlorine in tap water.
re: "Oh and you're absolutely right about the scripture reading, prayers and sunlight. Instinctively, with each breath my spirit leads me to exactly those same things. It's so nice."
This is really beautiful. A strong indication that you were meant to Water Fast :).
