Hi @taya ...I am assuming that you are able to bring the mucus up. ?? When I first started taking Clear Lungs, it was helpful in getting the mucus up. (that was maybe 2 yrs ago) Now...I have so little mucus that it is a rare event that I can get anything up from my lungs. I am not sure if I can attribute that to the Clear Lungs, nebulizing saline or the third possibility is NAC. Perhaps the combined effort of all of the above. When I first began, I would cough up green/yellow balls of what I assumed to be infection...now there seems to be nothing in my lungs or only a little mucus on a rare occasion, nothing like before. I intend to continue all but have actually cut back on my clear lungs to 1 every other day recently as there seems to not be a need. Is your sleep issue because you are coughing so much? I know when I was ragged from no sleep because of an overactive thyroid,(resolved) I would meditate. At least it would give the body rest. Kate
