my lungs have been able to breathe much better all of that time, no problems, no
coughing, now, all of a sudden, like within the span of two days, my lungs are bringing up junk. i went and got some mucinex the expotorant and cough suppressant type, and i can feel gunk, just coming up my lungs, its not helping and i've taken 4 of those today, should i use cough syrup ? is this normal ? the mucinex isn't putting an end to the stuff coming up.
