Joan, my husband found a humidifier during the night helped a little with the morning mucous.
Also, at about 2 years out from treatment, the mucous has become much less of a problem. I remember a year ago he wasn't even able to say "good morning" until he had a cup of tea, rinsed his mouth, coughed up junk...

Anyway, just wanted to let you know that it does get better with time.
