I was just proscribed mucomyst and have had two sessions inhaled. I like it (despite the smell) and I think it made my mucus thinner than 3 percent saline which was irritating my throat. I am in hospital at the moment and they are giving me 600 mg 20 percent 2 x a day. I hope medicare will pay when I get out. It feels smoother than salt solution somehow and the smell is tolerable.
