Need help with an odd problem
I don't remember quite when this started, but I'm sure it's been more than a few months.
Every night when I lay down in bed, just as I'm on the line between wakefulness and sleep, I notice that this problem is about to happen and wake back up. A few seconds later, my saliva production seems to go into overdrive, even if I swallow repeatedly, and I get an odd feeling at the back of my mouth, sort of up and to the left, just behind the last tooth. (I don't know how to describe it other than odd) A few seconds after that, I start to gag, and it gets increasingly worse until I take a drink of water. The longest I've lasted without water is around 30 seconds to a minute, at which point it feels like I'm about to throw up.
After drinking some water, it either goes away for the night, or it might happen a couple more times within the next few minutes, it varies. It only ever happens when I'm in bed, and the first time is always right on that line between wakefulness and sleep. It really makes getting to sleep a pain, because it takes 2-3 times longer than it normally would.
I've tried drinking lots of water right before I go to bed, and making sure to brush the area where I get the odd feeling when I brush my teeth before bed, but neither seem to help. It happens every night, without fail. It doesn't seem to happen if I wake up later and go back to sleep.
So, anyone experienced this problem themselves, or have any idea how to fix it?
