I think relaxing music helps to drift to sleep after a bath with maybe aroma bath beads or organic salts for your skin. I like the idea of clean nightclothes and of course fresh sheets; I like to make the bed early in the day so I don't have to do it at night. Actually, light floor exercises and stretches can help the muscles relax before bedtime, or swimming is a great knocker-outer. Sweet dreams! (I don't do any of this except make my bed early; take a bath late and think about being on a tropical beach)
