My husband ended treatment July 3, and the thick stuff started getting better about 3 weeks ago. He is still on PEG tube for about 50% of his nourishment. He used the generic musinex every 4 hours for 3 months, had a suction machine, slept sitting up, wore patches behind his ear for mucous, gargles with salt, baking soda water several times a day, and his Dr. Put him on prednisone for the swelling in his throat. One week on that and everything started getting better, he is being weaned off of it now, but we don't know if that helped the thick stuff or if it was because he started swallowing soup. I discovered he could taste and swallow potato onion soup, so he has consumed a large pot a week for the last 4 weeks.
