I have had this bitter taste for a few months now. had all kinds of test but no reason for it was found. have acid reflux for many years but have been taking prilosec for it. Taste is sometimes so bad it burns my mouth and makes me cough, goes away at night and sometimes stays away for a day. going to an ent man this week don't know what else to do
Pine nuts anyone?
I had the same symptoms last week and it turns out it was down to a certain variety of pine nut I ate a couple of days beforehand. All of a sudden everything tastes very bitter for about a week. I even tested them again (stupidly) and sure enough, two days later everything tastes grim.
I am having the same problem as you are. For the last 3 days I experience a bitter metalic taste in my mouth when not eating. I am visiting a dentist tomorrow for an annual check up and was going to mention it.
Did you find a reason for the taste?
Has it finally stopped?
