I been having trouble breathing. Every once in awhile when I sleep as soon as I fall asleep I wake up gasping air. Than other nights I sleep perfectly. Than during the day I occasionally will start having trouble breathing and feel like I have to take deep breaths to get sufficient air. Been going on for over a year. I’ve had numerous ekgs, blood work, chest x rays, ct scan, liver and kidney tests, but all of my results come back good. I occasionally get acid reflux. I also burp a lot.
