The guy who turned blue, took colloidal silver like water for like 15 years! I have used ionic silver (works differently, I think it takes a proton from certain bacterias and thats how it kills it) for years now, mainly like I use hydrogen and peroxide. I use it on cuts, burns (which they use it in hospitals for even though the FDA or someone tried to get them to stop). I use it to gargle with when I start to feel a sore throat (IT WORKS!). I used to use it w/ stomach issues, but I dont do that anymore b/c I am already on enough abx to kill whats in my guts (good and bad). I used it on my face when I was having acne problems. My grandma swears by it and she often carries it in a spray bottle and sprays the air when someone coughs (it was a joke at her last job haha). It could all be a placebo effect, but I find it works well for the uses I have found.

I am also interested in nebulizing it, but never will b/c its not sterile when made in my home (even though it has antibiotic properties). My dad and grandma and grandpa (all w/o CF) have used my old nebulizers or their own with colloidial (though what we make is actually ionic silver) when they have colds and stuff. My grandma is very into looking up alternative methods, but of course since in the US non of that is regulated it is hard to "risk" trying it. The stories sound too good to be true sometimes, but I agree though that a lot of the alternative methods are cheap and easily made which equals no money for pharm companies (I know thats a sort of conspiracy theory, but it doesnt sound to out of the question for me to believe if it was ever found to be true).
National Jewish in Denver (who deal with non-tuberculosis mycobacterias) I believe are actually doing some clinical trials with it inhaled, though last time I found out about it, there wasnt much being released. I would love to get in on the clinical trial though!
Lastly, it never hurts to 'search' the keyword ''silver'' because I know there have been posts on it before but I dont remember everything they entail.
I doubt your doctor will let you nebulize it though, my old adult doctor was very skeptical of alternative methods (ironically, she works for a pharm company now... the one who made cayston), and when I told her I used silver for my various reasons, she said, "Well all I see it doing is making your poop sparkly."
