I have used Biotene mouth moisturizer and it does interrupt the bad taste for about a minute. I used unflavored. I stopped using it so much after I got a suspected case of silent acid reflux. Long story, but it seems to have cleared when I let go of minty stuff I was using to address bitter taste. Switched to bubble gum flavored gum, that helps temporarily.

I also used Biotene nasal moisturizer, but may stop, since I’ve gotten 2 pimples in my nostril recently after using it.

I seem to have plenty of saliva and even too much when at dentist. So…idk. I do have dry eye.

I appreciate the input on Mayo. I’m going to reach out for consult. The ENT doctor and neurologist that I have seen just seemed perplexed and said that it’s (taste disorder) is difficult to treat. This leaves me very sad and hopeless. Plus, nobody else seems to have this problem. So, it’s lonely.
