do you sleep on your side or flat on your back?

Anyone from the two.. I change sides quite a number of times through the night.. Initially, I lay straight on my back, and then gradually start changing sides.. But I find sleeping on my side more comfortable than on my back.. I also find sleeping on my chest quite comfortable, but smbdy has told me that's not a good habit.. So, I have reduced that posture of sleeping to the minimum...

i sleep on my stomach with arms stretched. my husband says i sleep like a frog..lol.i usually put my pillows on top of my head and never moves all throughout.

i like to sleep with my belly flat on the bed, then my head twisted to either side. it is very comfortable. but i don't find this an ideal position because when i wake up, i get neck strain...gee...hehehe how can you feel good when you sleep and wake up with an aching neck? then this ache would spread through my head and i will get a migraine thorughout the day. hehehe

I sleep on my side with two pillows for my head and I hug a body pillow. I have a comforter, a quilt, and a sheet to keep me warm so I sleep like a baby every night!

on my side.
