I use the Cocoon Hyperlight, with a fleece sleeve/tube covering most of it and deflated just a bit. I'm also a side-sleeper. This has worked for me, although with any pillow I've used (stuff sack with clothes in it, Exped pillow) I still wake up sometimes and have to adjust the pillow or fleece.

This was the fleece pillow case I bought at REI, but it was too small in length to fit the Cocoon pillow, so I cut the ends off to make a sleeve. I'd be cheaper and fairly easy to sew a simple one from fleece scraps.
