I wake up every night at 2:45 and am done sleeping for the night. It doesn't make any difference when I go to bed I wake up at the same time. I am seeing a pulmonologist and he is having me do a breathing test during the day. Three times a day at other times when I have trouble breathing. I am really hoping he can figure out why I wake up at the same time everyday. I am a walking zombie. I try and stay in bed when I wake up. A Dr. told me if I get up and do something then my body will get used to that, and it will want to do that regularly. So I try and stay in bed and just rest. Don't know if that is working, but I keep trying.
