Brian,
Thanks for your reply, as usual. I think that I have been breathing through my nose for so long that I must , as you said, " learn " how to breathe through my nose. God game me this big nose for a reason!
Funny the natural stuff that we must learn to do. I ran into my cousin the other day on the driving range who is a radiologist, very experienced with head and neck cancers, and every time I spit, he kept encouaging me to swallow the mucous to practice my swallowing. It was easier said than done.
