Sleep, restful sleep, where are you?

My mind is so busy it’s keeping my body awake!  For several weeks now I have been awakened to nightmares of bears and kayaking  or restless legs or just plain staring at the ceiling.  Have tried going to bed early, going to bed late, eating before bed, not eating before bed, Tylenol PM and on and on.   But Mr. Sandman is elusive.  I guess I’m getting  enough rest to make it through the day and function fairly well, but just not getting that satisfying restful sleep. Oh how I miss it.  I know that sleep deprivation comes with parenting but it should not come this early!
