Sleeping

[George Cantstandya]

It could be your mattress. If it is an older one and you have been sleeping in almost the same position on it then it could have formed a bit to that position. That could make trying to sleep in a new position a bit more uncomfortable. You could try to rotate your mattress or flip it if it is double sided. My mattress is not double sided but is a hybrid and I rotate it every 3 months and I can tell it makes a difference in how comfortable it is.

I'm normally a side sleeper myself but have also had to sleep on my back in the past due to injury. It was not easy for me at first either. So I started reading in bed on my back until I was super sleepy, putting the book down just as I could not keep my eyes open much longer. That helped me.

I got a bit curious so I looked up some things. These articles might help:

Hope this helps.

Edit: I have also had issues over the years with getting good sleep, especially falling asleep. So I have learned a few things that have helped. I generally try to stop using cell phone and computers 2 hours before bedtime and no TV 1 hour before bedtime. While I stay hydrated through the day with plenty of water I don't drink any 2 hours before bedtime as well to avoid that feeling like I might need to go just when I'm wanting to fall asleep. I try to keep my bedroom a bit cooler than the rest of the house and let fresh air in through the window when weather allows. Again reading a book for a bit helps me as well. It tends to take my mind off the daily stuff that might be stressing me out as I try to sleep.

I guess what I'm trying to add with the above is that if you are in a state that can accommodate falling asleep easier then that might help as well.
