I don't have an answer for your question but I can relate to what you've just described...A couple of months ago I did the MMS detox..And I chose not to follow directions and added to many liquid drops...Needless to say I lived on the toliet for 2 days..That was Hell on earth...
The brown stringy things with a "lettuce" like appearance came out of me like crazy. So you're not alone with having those come out. I don't know what it is...It could be something as simple as backed up digested food or possibly a dead parasite...
Whatever it is we either have the same worm or we're eating the same kind of food...
