I stopped last night. I haven't had any form of crap like this in my chest and throat for as long as I can remember. My voice has been gone for 5 days(which, so happens, started the morning after my first CS/Nebulizer treatment. Still coughing like a champ, in pain, and with a little blood in my saliva. Other than the reddish tint to my saliva, I am not coughing any colored spittle.
