I've found some under wear that makes the cage far more comfortable. I now actually forget I have it on at times. So I now sleep almost normally. I maybe wake up one or two times more than I otherwise would. One thing that doesn't change is: when I am locked I feel a need to frequently hug or cuddle with my KH and rub the cage against her. (She loves this) I think I feel a need to remind her of my helplessness and to subtly say, "Don't forget I have this thing on."
