I have always been a snuffely person even as a child. Now I have Emphysema to contend with. Two things which have really helped me, apart from the usual medications.......my handy saline spray (called Fess here in Oz) - this helps unblock my nose, especially in the morning; and believe it or not, chewing gum - I get through packets of the stuff as it keeps my mouth moist, as I tend to be a mouth breather. It is good to keep my mouth moist when exercising and also stop a dry throat. Just a few thoughts.
