I have never had this happen in my life before.

Last night I kept waking up every few minutes because I was unable to expel air through my nose. It kept feeling like I was choking. I was completely capable of breathing in through my nose as well as breathing in AND out through my mouth.

But I was unable to breath out through my nose and it kept waking me up. I tried so hard to fall back asleep while mouth breathing, but it isn’t natural for me, but after a few minutes I would wake up choking.

I have never had this happen. I have no idea what the cause was and how to prevent it

Any tips or tricks, or even shared experiences would be wonderful!
