I tried doing a scaled down version of The Master Cleanse while doing a parasite cleanse (only 1/3-1/4 the amount of Maple syrup)it went all right for a couple of days, then when the parasite die off started everything went downhill-fast. The combination of released toxins from the cleanse plus the toxins from the die-off were too much. I became very weak and ill, my hair was coming out in bunches, I was having black out spells. When I decided to brake the fast and eat some fruits and vegetables, I was better. I still had some die off symptoms like severe headaches and cramping, but at least I could function. I personally do not recommend combining parasite cleansing with any type of fast.
