@poodledoc It makes my heart so glad when I hear of someone doing better because of the saline use. When I first came on this site many yrs ago; hardly anybody was doing the nebulized saline. I have repeatedly recommended its use since 2015 to our group, and now; most of us are using it. I have noticed a marked difference in the member's health over the yrs. They do not seem to be quite as sick and miserable with this mac as they used to be. Has anybody else noticed that?
