@cece55- As you may have read in my past posts I've been using C-pap for 20+ years and when I asked my sleep Dr. about the cleaning issues he just suggested just what you said about weekly. I rotate new or clean cushions for my nasal mask weekly and wash with mild soapy water using a product called Newport+ Home Lemon Verbena or Lavendar Sage that is infused with coconut & essential oils.
It's not overpowering, but gentle and leaves a nice lightly scented smell to my gear. As for the mental state of not allowing ourselves go to a negative place I have always focused on sort of my Zen position (not sure exactly want that means) but for me it means getting comfortable in bed on my back with my pillow slightly elevated and a light comforter over me and arms folded on my sides out of the blankets. I do some shallow breathing taking breaths in through my nose and then letting the air out slowly through my mouth. This helps me focus on relaxing. I do all this and if I feel sleepy enough I put on my gear and usually am asleep in 15 min. Other times especially when I have lots on my mind I do the big no no and turn on my TV. Usually Natl Geographic or History channel and set the timer for 15 minutes. I don't watch whats on, but it provides enough of a distraction that my mind doesn't kick in and usually I'm asleep before the TV goes off.
I have never been sick that I'm aware of because of unclean equipement and for me see no reason to add a SoClean to my night table.
