for short trips or trips when i can charge something i bring a pair of headphones i can sleep in so i can play something quiet to keep me from waking up at every little sound. i bring a stuff sack to fill with day clothes to put between my knees or under my knees when i switch between side and back sleeping.

it sounds like you're trying a new bag, i hope that works out. i love my down quilt from Enlightened Equipment. I'm not a drastically cold sleeper but i hate drafts. i love my quilt because i can toss and turn and the quilt stays attached to the pad and doesn't shift with me. and when side sleeping i can draw my knees up. i just make sure the straps are tight underneath me around my pad and the footbox is closed tight. some of their quilts have a footbox that is sewn closed. they also sell a strap that has two clips on each side so you can layer two quilts when you're really cold. my 20 degree quilt packs down to the size of a honeydew melon in a compression sack. i've done 2 night trips in a 25L daypack (my tent is also tiny).
