Hi DesertRat! People have very successful Liver Flushes either mid-fast or right at the end of a fast. (I have too!) No food in there to get upset. I, too, wondered about shocking my system with all that olive oil after no food...but it was just fine. The morning that I was to do the liver flush, instead of just drinking my lemonade..I had some fresh juiced carrot apple beet ginger juice. Just to get my digestive juices going. I drank my lemonade too. It went VERY well...Two times I've fasted before a Liver Flush and those were the two flushes that I felt the best!
Let us know what you decide....we'll be awaiting your results!
