It's a toss up between my side and back, but I think my side is more frequent. I like to hog the covers than twist them around me and between my legs. I also like to sleep near the window with it cracked no matter the temperature. I also absolutely in no way can wear socks to sleep. I also can't sleep without shaving my legs on the regular, my stubble aggravates me. I'm also very picky about high threadcount sheets and pillowtop mattresses.
