There is no way using a harsh laxative will clear your body of parasites, Gallstones or whatever else you have in your body.
If you want to clean yourself out, use 2 tablespoons of Epsom Salts mixed with water. Do this twice....wait a couple of hours in between. But, since you have already cleaned yourself out, go ahead and mix the olive oil/grapefruit and do the liver flush...........go to bed and see what happens.
You are so afraid of throwing up......think about this. If you have Gallstones (and 90% of ALL humans have them) and your Dr. tells you that you need surgery.......think about what all that involves. A little old Liver Flush in NOTHING compared to surgery.
There is a book on this website....Dr. Clark....on her forum. Go there and read all you can and get educated. A parasite cleanse in her book consists of three ingredients....and they are all natural.
Your phobia is natural and completely understandable.....but take the first step to control your own health. You can do it..........
