Can'tstop...Oh gosh...you sound so much like me. Like you say, sleep aids make it hard to function at work the next day, though I do resort to them frequently. The quality of sleep is not good, though, and I'm listless and tired all the next day.
I have a long history of sleep dysfunction, stemming from childhood. I recognize this, realize the history of it, but that doesn't stop me from dreading bedtime. Because of this, I'm wondering if your history with sleep has been good, ever, or if you have had difficulty with it for a long time?
One thing that has helped me in the past is exercise...not before bedtime, but several hours before. I'm just too tired for now to engage in it.
Love
Patty
