Thanks to everyone who responded tomy question. I certainly got enough information. Another question to the group has anybody tried the Master Cleanser before surgery, it consists of drinking a liter of salty water ( prepared to the secific gravity of human blood). After your bowel has empitied you follow up with a lemonade made with lemon juice sweetened with B grade maple syrup and cayenne pepper. You can have as much of the lemonade as you wish for as long as you feel you need to cleanse your system. I tried it before abdominal surgery(complete histectomy and ovaries removed) and my doctor commented that I had emptied my bowels very well and that had made his job easier. It made my recovery faster. Anyone else has experienced this?
