I'm having a bad problem with insomnia also. One night I gave up and actually took one of my Ambien instead of the Benadryl. I lay awake and go to sleep at 5 or 6 and wake up ant noon. I have even had an appointment in the early morning and gotten up at six and still had insomnia that night. So I don't think it is related to the time of day I wake up. My body wakes up around 8 PM. That's when I feel energized, my mind more alert. So last night I took a secret stash of an old prescription of Baclofen. I can't remember what the dose is but I take 1/2 a tablet. I slept so soundly that when I woke up I found my cat sleeping between my legs instead of at the bottom of the bed. I don't know what I will do when I am out of that secret stash
