When I drink about 1 1/2 cups of the salt water flush (ie 2 tsp/4cups) first thing in the morning. It cleans me out in about 2 hours and I feel amazing have tons of energy and do not seem to have to eat as much. I even usually have breakfast about an hour after I drink it. How often can I do this? Is it hard on your kidneys/ bowels etc? What are the risks?
