I am on a good schedule so I take my melatonin at 4PM. Then I am normally asleep by 7. I woke up at midnight last night. I was anxious so I took a 10mil melatonin and a valium. I'm just now realizing that may not have been the best combination. But anyways I got back to sleep right away until 4. So I slept pretty good. It seems I've had more good nights then bad nights lately.
