Sleep apnea due to narrow airway

For me, adjusting to a CPAP was quite easy. Any physical discomfort (which was minor) was easily ignored in exchange for finally getting some sleep!

Others have complained that the mask is uncomfortable. I didn't have that problem.
Others may find the machines noisy (after all, it is an air compressor), but to me, it's relaxing white noise.

Give it a chance. After you've gone through an extended period of sleep deprivation, you may find that using a CPAP is a godsend. I did, and still do.

Advice:
Take your time when being fitted with, and to, the machine and its various accessories, including a range of masks. A competent RT (respiratory therapist, or one similarly qualified to provide and to fit, and to set up, the various CPAP machines out there on the market) should brief you and instruct you on its use and care, and the best places offer to monitor you remotely (modern machines have a modem and record nightly stats on a SIM card, although you may have to ask for, and pay for, the SIM).

Once again, take your time and make sure you leave the RT's office knowing what to do. and with a mask you are pretty darned sure will work for you. Even then, many still trial other masks to get two or more that they can rotate through in case on type 'gets old'.

Second tip: practice wearing it and getting used to it two or three times each day for the first two or three days. Read or watch TV, or surf on the www while your machine runs and your mask is in place. This makes you less bothered by the novelty, but it also gives you an opportunity to fine-tune the fit. For example, the headgear straps stretch over time. If they do, the fit of the mask, and its seal, change. You'll get 'blow-by' and leakage, some of which often is up into the eyes causing fluttering eyelashes and being jerked out of blissful sleep.

Third tip: [besides practicing wearing it for an hour or more at a time...] some of we unfortunate PAP slaves find that, to our dismay, we're mouth breathers at night. If you wear the mask properly, even a full face covering mask, your lips and jaw slacken while you are asleep and the force of the air rushing into your nose may cause your lips to separate and air to leak out through them. There are chin straps available, but they're a C- solution for many people with this problem. In my case, I use a surgical quality tape, or most lately, and very successfully, the PAPMd strips from that site. https://papmd.com/ I have no interest or association with them, but my wife looked online and ordered me two pouches. I rolled my eyes (when she wasn't looking), but I was pleasantly surprised. Even better, you can scissor them in two lengthwise and get two strips of use out of one. Works for me, anyway, and I even get several night's worth out of one half-strip, so the cost is not so bad compared to 3M 'water resistant' and other tapes (because we all drool in our sleep, and if you tape over your slack mouth....)
Lastly, I would like to make a pitch for an extremely useful website called apneaboard.com. I am an 'advisor' over there, a high-falutin' title, but really it just means I know just enough to be a PITA for all the smart people. 😀

Thank you for your response! The unknown is always nerve racking and you have put me at ease!

Ahhh! Very useful information! Thank you!

You're very welcome!

Have fun getting your energy back!
