I was in a very similar pattern back in May through August. I only had a couple days of good, but did have a weird taste. It was sour or bitter, just weird. Then they found out my wrap was undone and my LES was wide
open. I didn't have normal heartburn either. I felt it in my left shoulder only. Almost exactly like it felt right after surgery from the gas in my belly.
Hope they get you fixed up soon.
