The Liver Flush will change your life! I promise. Most people use Dr. Clark's recipe which includes Epsom Salt, olive oil/grapefruit and lemons if you chose. Her recipe is listed on the homepage either under her name or on the left hand side of the page--click on Liver Flush (I think)
So, flush away and get ready to feel 100% better! But, one question--why are you waiting 4 weeks?
