@beegee..I want you to know there is hope for relief from the constant coughing. Many members will have suggestions, but I found relief by sleeping upright so acid did not enter my lungs. A low acid diet, postural drainage, and acupuncture to calm my coughing nerves have helped me get off oxygen and keep the damage isolated to one lobe. Do you have bronchiectisis and do you know where your damage is located?
