The songs without words that have odd sounds are great to go to sleep by, they absorb my attention and help me to relax and go to sleep. I guess it's my way of counting sheep.
I usually have to take a muscle relaxer to avoid unbearable pain in my head, neck, shoulders and back and keep muscle jerks down to just an occasional twitch. But this morning I haven't had to take it, now it is after lunch and I am going to take it because I am starting to hurt. But I have been listenning to this music most of the day. Music is good medicine!
