Thank you all for your replies. The mucous is getting less and less but there is an acidity taste in my husbands throat. He is complaining of a dry mouth now and as before. Any suggestions. I was thinking the mucous comes from radiation but I am wondering if it is from the chemo. We have water, ointments, oil to remedy the dry mouth but still he has to be awaken every hour when sleeping at night. He sleeps on our loveseat with his head hanging over his body. I bought a recliner (delivered Thursday) for him to sleep in. He cant sleep in bed because of the mucous. Sad state of affairs to see him like this. Thanks again.
