Thinking it was GERD from taking an increased dose of Fosamax, I consulted a GI doctor, had an endoscopy, which showed erythema in lower 1/3 of esophagus and
mild gastritis. I've taken high doses of Priolosec, Nexium, Zantac, Aciphex, Carafate. Nothing makes the taste go away. Certain foods make the taste worse - chocolate, tomatoes.
Checked with dentist - no periodontal problems causing the taste.
I do have a chronic postnasal drip - should I see if my sinuses are causing the bad taste?
