i have been having poop breath for years. i brushy teeth and tongue 2 times daily. i have tried many and visited several doctors but nothing worked. yesterday i started clearing throat with force and i gargled salt water. i also coughed many times. this reduced the bad breath a little bit and my swallowing improved a little. the problem is that i can not dislodge the hardened mucus in the lower throat. PLEASE HELP. HOW CAN I DISLODGE MUCUS DOWN IN THE LOWER THROAT?
