Hi, I have had insomnia in the past due to stress. Even prescription Ambien or Lunesta did nothing at all. Seroquel knocked me out but in a very bad tranquilizer a rhino way.

Try getting in as much hard physical exercise as you can, and see if you can push yourself to become physically exhausted. Physical exhaustion for me trumps the emotional stuff, and no matter what, I can fall asleep at least a few hours.
