Sleeping in a recliner or on the couch. The recliner forces me to not sleep on my side (I am a side sleeper --if I sleep on left, left side hurts; if I sleep on right, right side hurts). Also, when I sleep on couch I can distribute some weight on the back of the couch so not all weight is put on just my side.
I know these are drastic measures -- as we "should" sleep in a bed -- but I am much better in the mornings for it
