Hi I am 36, I woke up in the middle of the night, coughing and gasping for air. This has never happened to me before, shortness of breath, coughing up mucus, I took some cough medicine to see if that would help, but after half an hour, I feel like I can't lay down to sleep still because of the symptoms. I feel like I still can't breathe no matter how much I cough. I dont suffer from sleep apnea, and the cough is new.
