Good morning Faye, I am a great proponent of using the least amount of medication and supplements to support my health. For me, the Mucinex is an absolute because without it my lung and sinus mucus are the consistency of rubber cement, and have been since childhood. Due to the "sticky" nature, I was tested for Cystic Fibrosis, but fortunately I do not have it.

Do you have trouble with thick or sticky mucus when you are not ill? Or are you able to get good airway clearance most days?
