Mary Jane, thank-you for your reply. May I ask what your lung condition is? I have PF & BE. I have been diagnosed for about 3 1/2 years. Never had this problem until recent lung infection. My disease of BE creates a lot of extra mucus, does yours? If so how can we do proper airway clearance without being well hydrated??? All of the airway clearance helps to prevent reoccurring lung infections. I never had low sodium since diagnosed. Until the lung infection, so I’m assuming that was the cause. But is it always permanent. I realize it’s a double edged sword, damned if you do or don’t. Anything you want to call it. But how do you specifically manage your condition? I will gladly take any advice & help I can get. Thank -you.
