I'm not sure if this is BFS related, anxiety related, or TMJ related... but does anyone else bite their tongue as they drift off to sleep? I've done this periodically over the past year but lately I've been biting the *beep* out of my tongue. My jaw just clamps shut as I drift off and I'll either wake up to a sharp pain in my tongue because I just bit it, or I wake because I just clamped my teeth together narrowly missing my tongue. I was just laying down for a nap and I did this about 5 times in the span of 30 mins. Anyone have any insight on this?
