Maybe you need to need to experiment with various mattresses, maybe by adding a mattress topper. Many who move a lot during sleep do it because they can not find a comfortable position. I used to have carpal tunnel problems and wore splints to bed. This made it difficult to sleep other than on my back. I have slept with a pillow under my knees. It is easy on the hips and makes it easier to stay on my back.

I would love to get an adjustable bed so I can adjust it for best comfort and support. I know it helps because I get my best sleep in a recliner/easy chair.

Once I found the right mattress and pillow combination, I often wake up in the same position I went to sleep in. It also helps to not go to bed until I am ready to fall asleep. I am usually asleep within a few minutes of laying down. If not, I tend to toss.

Sleep has been quite a process for me. I used to be fearful of going to bed. I would have stressful dreams and wake up a wreck. So, for me, every effort was worth it. Once I learned how to sleep soundly, my neck healed up, my central sleep apnea is virtually non-existent and my days are much better. I believe my neck would get inflamed causing blood flow restrictions causing the sleep apnea. But, no sleep specialist ever agreed with me.

It is a difficult challenge but worth it.

My best to you.
