It's a fact that Rocket T. Coyote eats, drinks, and even sleeps rocketry. Here we see the bottom half of one of his "night survival suits" which insures that he awakens refreshed and ready to take on the day's challenges.

These space-themed footed pajamas were bought on clearance several years ago and are actually a few sizes too large. I had to hike up a foot of material otherwise the legs would slouch down over the ankles. Being over-sized is okay as the material is not very thick and another suit is worn underneath as I tend to layer up for Winter sleeping.
So my sleep system is like a fuzzy sleeping bag that can be walked around in. No blanket to throw off while tumbling about. Feeling no drafts, my sleep periods continue through the night, usually uninterrupted. Sounds silly, but it works for me.
