Something that my parents did was straight out of "Cider House Rules". The orphanage had a sickly boy, presumably from alcohol use by the parents, or something else that wasn't well understood in the 1940's. My father could make anything, although he was loathe to admit it. During a particularly bad spell for my lungs, I awoke inside a clear plastic tent, filled with steam so thick I couldn't see out. Humidity where I grew up wasn't so much percentage of water as much as a percentage chance there would be ANY measurable moisture in the air. Actually the humidity was typically around 5%, something verified by everybody's bone dry nasal mucus. In my case, the oxygen tent was hooked up for both steam and oxygen. Fortunately for me, my lungs improved considerably by the time I was an adult.
Water in the form of extra hydration usually translates to a better quality of life all around when it comes to CF. I don't like salt and I don't really like drinking water which doesn't help when I am sick. Once I get into the routine of good hydration I drink a gallon a day of water and non dehydrating liquids. Doctors don't hold our hands and to my surprise, they don't bother harping on simple things we know help. Doctors tend to be delighted when a test comes out negative, usually for good reasons. We don't want bad news and there's a disconnect when they find nothing wrong, and we are certain there is. We don't want to hear that we need new lungs or something life changing, but we want answers when we feel something isn't right.
Something so obvious I forgot the answer to a particular health issue could be "you have CF". CF is still just treating the health issues that arise from our tiny genetic error.
