I have some but still haven't tried it. True the problem may be old fecal matter in my colon but I just don't know anymore. With me, it's so weird how it started and the odd things that trigger my smell. I poop every day atleast once. Sometimes my movements are a good size and other times they are smaller or thinner. My odor smells like rotting food sometimes so I think I ma having some problems with my digestion or something and I don't see any type of laxative helping that.
