been up all night

I have trouble sleeping also. My mind refuses to shut off and even being a sleep it keeps on working. Needless to say it doesn't make for quality sleep. I have a rainbow of sleeping medications but have to use one for a while then switch to another. I also suffer with a bad back and shoulder pain. I have began to overcome the rotator cuff tear shoulder pain. I have always slept with my arm under my head. I was researching and found out that keeps the shoulder from healing. For the most part I have trained myself to keep the arms down and haven't done the surgery the Drs wanted.
