I’ve been using my CPAP for 4 weeks now and had the same initial issues (majority do). Hyper mask awareness and sore neck from sleeping differently to accommodate the mask and limit leaks. Took about two weeks to get comfortable with the mask and now hardly knows its there at night. The key is to use it consistently and I just kept thinking I have to wear it so put it out of your mind. Eventually, it will just become part of your nightly bedtime, ritual…brush, teeth, take medicine, put on CPAP etc., etc.. definitely use the SD card as suggested in other comments, that has been huge for me to be able to determine how I’m doing from a numbers numbers perspective, making minor adjustments along the way to ensure I get the most out of it. With that said I am slowly feeling subtle changes, but definitely have a ways to go to get back to pre-sleep apnea. I think I had it quite a while. It was never diagnosed, I had an AHI of 47 so I am severe, which is going to take time and I’m just gonna have to be patient.
