Hi, Mr. Flush...I only got the green oily pea sized "balls" on my very first flush..subsequent flushes produced tan "balls" that I described as being composed of sand and wax/grease. They were firm enough to pick up and handle, but I could squish them if I tried. There were also triangular small hard stones of varying colors that I didn't realize came from the liver ducts until I saw some pics here..the next day lots of debris that looked exactly like mushroom pieces..Folks here assured me they were flukes. For all the naysayers out there that believe the lemon and olive oil create "green soap stones" why don't I get green blobs? My olive oil is certainly greenish..but my "stones" are tan and brown and black. HMMM? Best of health to ya!
