yes, I have COPD and I am currently on oxygen while sleeping and I took a test without the oxygen and my levels went to 44 4-5 times during the night. I told my doctor but he didn't seem to worried but I am. I asked him if I have Sleep Apnea and he said that he would contact a lung doctor but haven't heard anything yet. My question is I don't feel rested when I get up in the morning and sometimes I fall asleep while sitting in church, and sometimes while driving. Is it possible that I have sleep apnea since I COPD on the border line of moderate to severe. Please Help
