I have a few solutions that I've used my self to get more sleep. Most of this stuff came from serendipity.
When I'm too hot, I use one of those cryopacks wrapped in a damp wash cloth and move it around my neck and shoulders. Works best if you let it melt a little till it gets mushy.
Dry nose: vaseline up the nose. If you sleep on your back (doesn't have to be flat-out) some of the stuff gets soft and runs into the sinus just above the nostril.
At night I rinse my eyes with lotsa Bausch and Lomb eye wash then put in my eye drops. I found that my eyes attract gunk since there are no tears to continuously flush the dry eye of SS. Also use throughout the day when it feels like I need it. Use my eye drops every two hours.
At night I couldn't move, had terrible pain. I kicked dust at my HMO and bulldozed my way into a pain program. At this HMO the program was geared to chronic back pain, fibro, and physiological pain reactions. For their criteria, I really didn't belong. The instructor didn't like me very much. Oh well, I'm my own best advocate.
However I did come away with some tips for relaxing and psychological stuff to work with to ease the pain--really helped with panic of pain onset. And, came away with oxyC every 12 hours, only 60 prescribed at a time. Usually only take one a day. During the day I take acetomenophen arthritis for pain--time released--my own solution.
This may sound silly, but I hang up a load of freshly washed clothes in my room--as it dries, moisture is released--never could get a humidifier to work. Bunch of bath towels works best.
I make sure that I'm up and around enough during the day to feel tired when I go to bed. This can be as little as small tasks around the house or walking (I walk my dogs). Something to keep me moving through out the day.
These are things I've found out for myself. Hope you find something in here that can work for you. This stuff all or some of it works or doesn't work most of the time. There are still times it doesn't--not 100%
You got to hold on.
