Yes, Cpaps are hard to get used to, but believe me when I tell you they are well worth the effort to get used to. Now I won't even lay down for a short nap without my cpap.
I have my tubing covered with a fleece covering that I bought where I got the cpap. Not only does it keep the tubing from catching on everything and making that sound, but it keeps condensation from forming inside the tubing. Believe me that can get scary if a lot of condensation accumulates because before you know it water is dripping inside the mask and you feel like you're in a shower or drowning!!!! I mention condensation because I keep my bedroom cold, summer and winter, and the warm moist air from the cpap machine condenses in a cold room. Also if the tubing should touch you during the night as you toss and turn, the tubing feels soft and cozy, unlike the cold snaky feeling of the bare tubing, :-)
Also, I discovered that I wanted a 10 ft tubing instead of the 8 ft. It gives you more ease to roll over etc. and less chance of pulling the machine off your bedside stand. If you get the 10 ft tubing and you want the fleece covering, you'll have to get 2 coverings to cover the tubing. Hope this answers your questions. Please keep on trying to get used to the cpap - it could save you life. Sleep Apnea can cause heart attacks and strokes. I've just read the above post, and I want to add that your machine should be level with the top of your mattress or with your head. Also I suggest that you do have the humidifier on your machine because if you don't you are going to wind up with a very dry mouth and throat and that's not healthy
