Still very new to all this but the first week was awful - then they changed my mask to a full face mask and from that day I slept average 7.5 hours with no AHI at all! Been three weeks almost and I feel brilliant - if someone tried to take my dream-machine off me I'd kill them! I absolutely love it!
Hope you soon experience the same feelings - good luck
My best night of sleep in years was the night of my sleep test at the hospital. I've struggling on finding a comfortable mask that does not leak.
I've been using my CPAP for about 7 months. I started to notice a difference within the first 2 weeks or so. My AHI fluctuates somewhat regularly but it's around 5, down from 32 during my test at the clinic. I no longer wake up gasping for air, and while it used to take me 4-5 hours to get the stuffiness out of my head, now I awake with a clear head. I usually wake up about once a night, but that's due to dry mouth and so I take a drink of water, roll over, and go back to sleep. In all honesty, I believe that my sleep apnea has affected me most of my life and my only regret is that I didn't start this program about 40 years ago.
My machine got delivered Dec 9 2015 and Dec 10 was the best I felt in over 10 years. While the euphoria of the first few nights has worn off the new normal is hugely superior to my pre-APAP days.
I just purchased a 2nd machine out of pocket as a backup, and as a lighter anecdote I recently fell asleep before wearing the mask and my wife could not believe how loud I was, and then reflected on that is how she has lived with that for so many years. How quick they forget.
Now she insists on carrying my machine wherever we travel, so now she can't do without it either.
