wow. I am so sorry you endured that!!! No wonder you wake up at that time.

I also have C-PTSD and had trouble staying asleep. I also have DID and my alters would get up at night and such. I finally had to break down and allow my psych doc to put me on Trazadone. For me, that is working.

Another thing you might want to try is EMDR therapy. Eye movement desensitization. nIt helps to actually process the trauma inside the brain and move the memory from the short term memory locations over to the long term memory sections which are further away from the hypocampus. That means the memory stops being an active threat.

Another option to try would be to set an alarm to go off about ten min before you would automatically wake up... make it something very soothing like nature sounds.... That will give your brain something new and calming to anticipate to overwrite the warning that is etched there right now.

big safe hugs for you!!!!
