PTree, I decided last night to do another enema because I was not feeling well. My energy was taking a nosedive and I felt as though I was going into a detox. So, I figured if as you say there is a connection with the colon and back pain, an enema might help there too. Well, the stool I flushed out was initially a small bit of very loose, light colored stuff, when I swished it around, it seemed to be a piece of phlegm with the loose stool attached. After that I flushed out some very dark pieces which seemed to be rather hard. But the color was kind of murky black. Is this plaque? They were bits and pieces. Also, I passed a few (about 3-4) small, pea-sized black stones. I think I may have killed off some parasites or had some die-off reaction. What I forgot to say yesterday was that I had started taking the parasite formula yesterday in between the shakes. Well, late in the afternoon I started getting this pain immediately below my stomach. It was quite strong, I had to unzip my jeans in order to sit at my desk. It lasted a couple of hours and then I started feeling queasy and very tired. I did sleep very well last night up until about 2:00 am which is when I am usually very restless and the pain in my back starts up. I was taking an Epsom Salt drink at night before I started the Colon Cleanse and it helped, but did not stop the cyle. Any thoughts on this?
