Your poor friend - Hope Teleman returns to give his expert advice. I have been that bad three times and can't remember if I had fevers but I felt terrible. The first time about 10 years ago I read in Clark's book that if I had the symptoms she described to do a liver cleanse immediately as I could become very ill if I waited so I did the cleanse but it was rough to do. I threw up the grapefruit oil mix, and the Epsom Salts did not result in a purge. I waited a day and tried again and was able to keep the g/o down but got no stones. I felt a little better so waited longer and started doing Liver Cleanses every two weeks and eventually the stones started coming out. I have an underlying intestinal problem and make lots of stones so about 5 years later I got clogged with stones and found I could do the cleanses 3 times, every other day and then two weeks apart. I also learned that when I was in crisis that I didn't have as many problems if I didn't eat the morning of the cleanse and drank 3 to 5 glasses of water. Also preparing by taking Epsom Salts or Milk of Magnesia the evening before the purge helped.
You might want to go to the DR Clark Information Center for more information about liver cleanses. Her descriptions are very clear and helpful even if you use a different method.
