coughing so much-need suggestions
don't forget that that baby is pressing up and irritating those lungs - I coughed to the point of puking throught much of the end of my pregnancy - it wasn't as exacerbation, just irritation - you might find once the baby is born the coughing resolves itself (and I would do the vest twice a day - no sense in letting things catch up with you). I do do my meds at the same time as my vest to save time, as it is precious with two little ones - but that isn't the best way to do it.
Mucinex (the guafinisen only, not the one with the suppressant in it!) is fine for reight now to help loosen up whatever is in there.
