Michelle,
I didn't have one for radiation but had one after the trach surgery and now sure wish I had had one during radiation. It sure beats pulling it out with your hands. My mucous was usually the worst in the afternoon. I rinsed with baking soda only. Everything already tasted so salty I didn''t need any more. I also had horrible thrush and rinsed with Nystatin. It's been a long time, but I think the brand of water your husband is drinking is one that gave me problems. I think I settled on Great Bear. You just might try a few different brands and see if any work.

Take care,
Eileen
