The very first liver cleanse I ever did as directed by my Naturopath called for fasting on apple juice with 1/3 cup olive oil drunk twice a day. A potassium rich veggie broth was an option at night, but I had trouble keeping that down. At the time my gallbladder attacks were so bad I would have probably been rushed to surgery if I had insurance. (I had to quit my job after a back injury) This cleanse did not use any Epsom salt, but called for a daily coffee enema preceded by a fresh water enema.
This was a very powerful cleansing flush and I passed dozens of hard, almost black stones, some with a thin white film on the outside. Trying to find an easier version of this cleanse is what eventually led me to Curezone. This is the nearest I have ever done to an olive oil fast, but consuming 2/3 cup of olive oil every day for ten days was quite an experience. I lost thirteen pounds during that cleanse despite all that oil.
I wonder if your body is leading you to a very deep level of liver cleansing.
