Why do i wake up during the night choking and unable to take a breath? it makes me teary eyed as well. no cold or symptoms. also neg sleep study.

Sleep apnea: Sleep apnea might be a cause or symptom. A disruption in the sleep process is the problem but obstruvction of the airway and thus reduced levels of oxygen the long term consequence. A medical evaluation is needed and possibly a sleep study to monitor breathing, heart rate and rythm, brain waves tobrule out seizure activity and levels of blood oxygen. Get this done and feel more refreshed in am.
