sue, forgive me if I have this question in the wrong topic. But I recently switched taking a 3% saline solution to a 7% solution. Its so much stronger and I cough more throughout the procedure and discharge mucus. Is this normal? This is my second time nebulizing. I do feel that I will probably adapt to it. I have another friend that told me 7% was too strong for her and her doctor cut it down with an added solution. Like all of you Im hopping that 7% will cut down on my bacteria count. Hauoli
