I have some sleeping issues, but it's mostly the soreness in the morning that bothers me. I have ways I go about laying in each position that I now literally do in my sleep. It also helps me to cuddle someone, I will explain that, too.
Left ('good') side: For this, I need 2-3 pillows. One pillow lays flat on the bed and meets up with my shoulder. Another, fluffier pillow sits on top of it, and goes between my shoulder and my neck. I bend my left arm and put it somewhere near my face, usually under both or one of the pillows. My right ('bad') arm either bends and goes under my face (it looks funny but feels good to spread my fingers so I like to put my hand under stuff) or around a third pillow, or my fiance's arm or chest if he's the right distance from me. The 3rd pillow/fiance used to be a giant teddy bear, but my mom is holding him (my teddy) hostage for some reason.
Right ('bad') side: I usually just use one fluffy pillow under my head for this one, and bend my elbow and flatten my hand under my face and pillow. In this position, if I don't push my hand under my face and pillow, it doesn't reach the bed, so it stays uncomfortably up until I push it somewhere. My left arm does whatever is comfortable, which is usually bend and curl up and push a big wad of blanket in the crook of my neck and left shoulder. This is how I usually fall asleep, however I get heartburn worse when I lay on this side for some reason.
Cuddling: I usually lay on his right side. I lay on my left side and put my head on his shoulder and his arm kinda goes under my neck (creating the same sort of effect as the 2 pillows did) and then my right arm rests comfortably propped up on his chest. This is comforting not only because I love him, but I think it puts my spine and right arm in just the right position that I relax my body. He sometimes has a hard time sleeping when I'm on him like this, so once I'm fully relaxed I usually roll over to my right side and completely fall asleep the way I listed above.
Stomach: I lay all sorts of ways on my stomach, most of them involv my arms being up, and one of my legs being bent. I feel like thi should have illustrations lol...
hmm, here:
Terrible illustration is terrible lol anyway, that's basically how I sleep on my tummy, but again I will usually pull that right arm in under my pillow and head so that my hand has a little pressure on it and my fingers straighten out.
On my back: I don't sleep long at a time on my back, but sometimes I need to lay that way to fall asleep cuz everything hurts and it's the most comfortable. I usually interlock my fingers over my chest under my boobs so that my arm is propped, until I'm half asleep and then I let go and just kinda let it slide down onto the bed so my elbow reaches the bed and my hand rests on my stomach, my left arm stays there though because my elbow can reach. Sometimes I put my arms above my head. In this case, I either find a pillow to put under my right arm so that it doesn't sit there at a weird angle not laying flat on the bed, or I again push it (usually I use my other arm to get it there) under my pillow and face so my fingers flatten out. With my left arm I'll either do the same or leave it on my chest.
The problem I have is a lot of mornings I wake up sore, especially my shoulders, though sometimes my back and legs. These methods usually help me fall asleep though, and I'll sleep ok through the night. (Though I toss and turn to get to the next position during my sleep, I also talk in my sleep, sing in my sleep, hold my breath once in a while, and snore once in a while.)
