Elen,
Hello this is Kitt. Welcome to Healing Well and the A & P Forum.
I agree with Lyn, deep breathing exercises and muscle relaxation techniques help to relax your body and mind.
I would throw in so easy listening music or if you have a favorite CD that soothes your soul, try that.
For me, a nice warm soak in the tub is relaxing before bed time.
Hope something here works.
Again a Warm Welcome.
Kitt
