Breathing stops while falling asleep
Some nights I experience an irritating sensation in my chest set in as I'm drifting off to sleep, on the other hand most of the time the sensation feels really mild and my breathing just stops. It seems like the mechanism that switches from breathing while awake to involuntarily breathing while asleep fails and I can feel it malfunctioning. Either way it brings me to full alert and at that point, all symptoms vanish. I do have occasional asthma.
