This will probably be my last post on CPAPTalk since I no longer need the CPAP machine anymore. Two months ago, I purchased a boil-and-bite MAD device that pulls your jaw forward as I didn't want to lug my CPAP machine around when traveling overseas. To my surprise, the first night I used the device, I slept soundly and woke up more refreshed than I have ever in many many years. This was the same night after night, until I retired my CPAP once and for all. Now before I move on, I know that there is a crusade against anything non-CPAP on this forum, and I understand it. I was skeptical that such a simple device could cure my problems too... That's why I bought an overnight oximeter to see what was going on. The results were quite amazing.

As you can see, my heart rate was quite stable with only variations where I guess I was in REM sleep. The oxygen saturation did not drop below 92% at all and mostly stayed above 95%. This is coming from someone who had an AHI of 37 and lowest oxsat of 69%!
So to those who are still struggling with CPAP, it probably wont hurt to look into one of these devices. I'm eternally glad that I did, and I hope that they can also help you.
Now I know there will still be some people who will shout "witchcraft!" and brandish me for not using my CPAP any longer. But to me, the oximetry results and the burst of energy that I get every morning simply speaks for itself...
Best wishes to all.
