7th and 8th flush strange results...

Hi all

I just completed my 8th flush. Actually saw some pretty good size peas green stones. They are usually small or not at all. This flush though and the one previous resulted in more junk than stones. The stuff reminded me of bits of grilled onions. Loads of it. And also huge amounts of mucous. Looked liked I had a monster cold and blew my nose through the rear! Is this mucous a former inhabitant of the liver or coming from the bowels? I only see it during the flush and with the odd onion looking stuff.
ANy ideas? If this stuff had been stones I would have guessed it at several hundred. But as I said, not tomany stones with this junk.
Thanks.
