everyday for about the past month i wake up and feel something in my throat. its very uncomfortable so i start trying to hack it up. i get it from my throat and it feels like it moves to my sinus area and then i start to gag and feels like choke and finally spit it out. disgustinly, it hard chunky brown mucus. i have tried turning the heat down at night, getting a vaporizer in the room, sleeping with the AC on and even with the window up in the middle of winter. its so uncomfortable and disgusting does anyone have any ideas???
