Q: Wondering if you could help. apprx 4yrs now I have been living with SOB daily? I am 39yrs old and awake at night from a sound sleep unable to capture enough air? sleep study negative for apnea. Cardiac stress x 3 negative. Ct scan of chest negative. PFT's normal. I am able to exercise fine x 3-4 a week? tried lexapro for anxiety, did not work? Yawn or try to capture a yawn aleast 3 times in 5 minutes? called 911 twice this past month because it is that bad? I am an RN and would not pull the trigger if it wasn't necessary!
