I too had problem sleeping,at times I'll be lucky to get three hours, I then spoke to my personal GP & he gave me "amitriptyline" and were advise to take two hours before bed time, but never drink coffee or tea after 5 pm or you will be counting stars, now I sleep about six hours a day ( alarm clock rings) but about 10 hours on weekends, I think this is anti-deppressant drug but man this thing works like a charm.
