@sweethighland I've always nebulized with 7% saline, nothing less. And my airway clearance has only been lying on my back and I can clear my airways that way. I've never used a vest, just the nebulizer. I use to nebulize every day but now I do it every other day. I was diagnosed six years ago but have had no progression for the last four years and I attribute that to the saline solution and exercising six days a week to keep my lungs in shape (as prescribed to me by best friend who is a doctor and when she heard about my diagnosis six years ago she said I had to exercise every day so I did what she said. She's smart.) I did take the big three antibiotics six years ago for one year but I really don't want to do that again if I don't have to. Hope that helps. Nan
