When I was around 18 years old, I started feeling a bitter mouth during sleep. At the beginning it was only discomfort, but it evolved to having to spit the saliva inside the mouth to having to wash my mouth several times during the night to having to wash it with toothpaste.
This was progressive and now I am 50 and washing my mouth is not being enough to mitigate the taste any more. The taste is so bad that there was a time when I would try to spit it out during my dreams (that action was actually part of the dream) and would spit it involuntarily on my pillow.
With time my body got into the habit of waking up when the taste was bad enough which I do several times during the night now. I have consulted with dentists, throat doctors, done several tests and exams, but nothing substantial that could be causing the problem was found.
Now the only way to stop the problem nowadays is to chew a mint gum after I wake up the first time, but this is also a problem because the strong taste of the mint wakes my up completely and I can't fall asleep any more, which makes me drowsy during the day. The only exçeptional information I could provide is that my saliva is quite thick, even during the day, but tests showed that the amount of saliva I produce is normal.
I have searched on the internet and can't seem to find similar cases. Is there anyone with symptoms like these or that has studied a similar case that could help me
