Feel better by 3:00 pm

[bibj12]

I have only been using a CPAP machine for about two weeks. I feel very bad when I first wake up in the mornings, like I haven't slept for days but by about 3:00 pm I start feeling a lot better - more rested and alert, and feel good the rest of the day. I can even stay up till midnight and feel good although I don't do this often. Then after a night of using CPAP I feel horrible again and have to drag myself through the day until about 3:00 pm. Has anyone else felt like this?

Check my signature line for software information. I have links to SleepyHead which will work with your machine.
Let's see what your reports say is going on during the night. Maybe something is not optimal.
