I am a newbie here and just getting traction on all the traditional air clearance protocols, but in my rather dramatic case, I have found that eating warm soups almost exclusively, and large quantities of very warm water keeps my secretions flowing and prevents me from having violent coughing jags like I used to have in the past. Now that I am revving up my aerobic exercise, and my airway clearance breathing exercises, things have been slowly improving. I am very prone to hemoptysis, and one way that I gauge my progress is to not have those bleeding episodes and what I describe is apparently helping. I walk a very fine line in my protocol.

Hope this helps.
