last night I just couldn't fall asleep and I just wondered what positions other people use to fall asleep.
Normally I lay on the belly and head turned to my left. My left arm is under the pillow.
The next best option for me is head turned to my right with the right arm under my pillow.
Then sleeping on any side!
The position I cannot fall asleep at all is when I lay on my back. At the hospital when I've broken my arm but wasn't operated yet and had to stay the night over, they normally put you on your back. To fall asleep I have then totally turned myself, rolled on my broken arm (well, the wrist was broken) and fell asleep that way...
The next morning my whole arm was numb. Probably not a bad thing before the OPs since I hate needles!
