I could not tell I had neck instability except for the symptoms I experienced after I slept in poor posture, especially if I fell asleep in the car or a chair.

The worst was trying to sleep during an EEG with sleep session. The rolled up towel pillow under my head forced by chin to my chest. The inflammation interrupted my breathing, even when I was wide awake. This event caused me to consider my symptoms after other bad posture periods.

When I tried sleeping with straight head and neck position, the quality of my sleep and the days after those good nights of sleep improved dramatically. If I rolled to a bad position, I would have stressful dreams and have a stressed look on my face.

I spent a lot of nights getting a good night sleep in a recliner chair.
