I try not to go to bed until I am tired and then I have a few tricks that help. I think I move maybe 2 or three times during the night but I know if I was tossing I would not be able to get up,,, I keep a water bottle on my night stand and when I wake up wanting some water it looks like it is a mile away from me for some reason and I wake up in the morning wondering why I was too freaking lazy to reach for it so getting up might be like pulling teeth for me, good thing I don't get that restless at night. Possibly my meds help me sleep so that is a good thing too.
A person has to ask themselves, are they tossing because they are uncomfortable or because they are just not tired or even if it is because they are nervous about not hearing the alarm or about the next day, maybe work is on the mind keeping them awake. I know if I keep my room comfortable and clutter free I seem to sleep much better. I do remember when my sister and I were allowed to make our bedrooms in the basement as kids (which was really cool for us) we had a nice set up but there was more stuff down there and I found myself looking at things in the dark and seeing different figures from it. I know just from thinking back that I probably lost sleep over it but who is counting when you are a kid... I am a big believer that if your most important room in the house is your bedroom you will find your best rest in there, and that means decor as well as comfort and warmth or even a breeze. I have other rooms in the house that are my rest area including a room with a hospital bed that has lift motors on it and if I have a pain that needs elevation I can go in there for a sleep, some might just need a comfy couch to lie on for a restless night. I know a lady who has a private room with a day bed and all of her very own stuff in it and she sleeps in there if she is being hit with an insomnia thing.
