That bad taste is my primary symptom. I get heartburn from time to time, but the main thing I notice is a bad taste in my mouth. FWIW, it doesn't affect my vocal chords, make me cough or wheeze, cause pain, or give me any of the other symptoms commonly associated with LPR. Two doctors have diagnosed it as GERD, though. I've had the bad taste with and without PPIs, though PPIs seem to help overall.
