i have the exact same thing, with excessive amounts of sticky saliva and flem, constantly throughout the day i have to spit, and im sure people become disgusted with this.. but it chokes me so im forced to.. when i cough up the flem i can smell the feces, or just a foul smell, i have also coughed up small stones that smell of feces but this occurs rarely, an overload of mucus in our bodys perhaps? but from what i dont know.. i notice my BM's have mucus in them aswell.
