I have been on BIPAP for 9 months. I am having same experience as you are. I can sleep 8 hours and still feel tired, exhausted , It is treating my apnea. I do notice an improvement in sleep. I sleep well with it on. I was waking up with heart pounding and now I'm not. The nights are usually good but the days are terrible. Feel exhausted all day. I was diagnosed about 10 years ago and couldn't sleep with it. My doctor ordered a home sleep study in December and was shocked that my apnea had gotten a lot worse. So I have really tried and am proud of myself that I have been able to stick with it but think about giving up because I'm so tired.
Do you have any good days? I do have some. I've been keeping a journal and during a month period I feel pretty good 15 out of 30 days. That is the only thing that keeps me going.
I have been on Bipap for 8 months. I sleep pretty good with it but still feel very tired. I have been using it every night usually about 6 hours and they take off when go to bathroom but don't put it back on. I have tried it both ways on after I get up and off. Feeling very frustrated. Anyone have this problem. I slept with out Bipap last night and feel horrible.
