The only thing that helped me was time. I spent a few weeks tearing it off my face (unaware until I woke) and this gradually subsided. Eventually your mind (subconscious? sleeping?) will start viewing the mask as normal, and its absence as abnormal. In my case it took around 4-5 weeks to get my face acclimated to the object strapped to it. But as others will attest, it was so very, very worth it. The sleep now is a godsend, and has given me “my life back”. The downside is you’ll quickly become dependent on it, and will dread doing without.
If you’ll tolerate a bit more advice: Over time you will need to replace masks/hoses/etc. Do this well before any failures and store the older parts as spares. One day you’ll accidently suck the hose into the vacuum, or roll over and break the entry elbow to your mask, or any other imaginable oops. And with a set of spare parts, you can cobble together enough to sleep until the new gear arrives. On my (rare) airline trips, I even pack a few of the more delicate backup parts in my checked luggage. The mask is notoriously fragile ime, and having extra little clips, elbows, and whatnot can be a godsend.
Regarding new gear, I would recommend joining the cpap.com site. Even if you have no interest in the forums, they can get new gear to you quickly. Once you settle into a pattern, you’ll find it very easy since they save your size and preferences. When I need new mask, reservoir, hose, straps, filters, etc. it’s all there and just a couple of clicks between the supplies and my front door.
A few other bits of advice from the nose-hose brigade…
-Try a longer hose next time you order. It gives a lot more freedom if you move about in bed much.
-When cold weather comes, you’re likely to hear gurgling in the hose in the middle of the night. This can be fixed by either a heated hose, or just turning down the heat in your humidifier.
-It’s likely that your cpap has a 12V car adapter either provided or available. I would recommend getting this, and finding a deep cycle, medically OK, 12V AGM non-spill battery as a backup. I keep one of these ($110.00) in the bottom shelf of my bedside table. It can provide 3-4 nights of current for the machine in case of power failure. I also take it when camping/etc.
-I take my hose and mask into the shower with me each morning. They’re washed and thoroughly rinsed along with me, and I hang them over a towel rod to dry all day. This has worked very well for 6 years and I have no problems with mold or ick in my gear. The various mask/hose cleaning machines (SoClean) aren’t really that effective and are usually a waste of money.
I’ve never found an easy way to travel with mine, at least not in the traditional airport/motel sense. I’m either trying to protect it from overenthusiastic overhead bag stuffers, fit it beneath my feet, and (in some cases) repairing it after hotel maids knocked some part off a towel rod or counter. I leave it to others here to give advice on that.
Best of luck! It will be worth it in the end.
