For at least 20-25 years I have not slept with a pillow. I have a pillow on my bed but I haven't used it under my head in over two decades. Sometimes I'll tuck it under my arm for some reason, but never under my head. My head rests directly on the mattress. I'm sure Mike Lindell won't like my sleep habits, but it works for me. I find this to be a pretty unique habit, but I'm curious if there are any other GHers who don't use a pillow.
