I just did 29 days of Master-Cleanse and yesterday/today I did Liver flush. WHAHOOO... This was my 4th Liver Flush in 1.5 years but this time the stones that came out were HUGE! One was the size of extra large double peanut in shell about 2.5 inches lond and .5 inch wide, about dozen of large peanut size ones tens of pea size and hubdreds of sand grain!!! I mean this stuff was just comming out of nowhere. The large one was hard and when broken looked like a dark green crystal and shining. Well if this stuff sits in your liver no wonder people have some problems.
