How can I stop my mouth becoming dry during the night? For some reason I get dried out every night. If I drink water I just wake up again a couple hours later, piss it out, and my mouth is dry again. I have bad tooth decay for some reason and even though I brush, floss and take mouthwash before bed, I'm worried this night time issue is causing it (otherwise I have no explanation why I get all these fillings and normalfags who eat multiple meals every day and eat all their cakes and treats are fine).

And no, I don't have diabetes. I've had fasting blood glucose tests done every 6 months for years because of this night time thing, and I've tried getting the proper diabetes tests done but my doctor's not going to do it for me because he doesn't think I have diabetes (you only get the glucose/insulin-response tests if your fasting blood glucose levels are high enough to indicate diabetes or prediabetes).
