Hello fellow overactive phlegm production sufferers! These all sound so achingly familiar to me. Been at least a decade for me with the chronic cough and throat clearing. What started as a GERD diagnosis has now morphed (via self-diagnosis through research) into LPR or laryngopharyngo (sp?) reflux. And finally there is more info out there on it. No solution yet but more hope there will be. Gaviscon Advance is my latest find for overnight cough.
