I can relate but I would suggest you not try to put a PTSD label on it.

I find I fall asleep best by occupying my mind with something comforting or mundane. Good music or a TV show that is not over-stimulating helps me.

I usually fall asleep watching TV then wake up shortly after and go to bed. I do not do well going to bed and then trying to fall asleep. The music I like to go to sleep to is so repetitively annoying to my wife that I can't use it in the bedroom. Besides, my body's antics as I fall asleep keep her awake.

Sleep specialists suggest not going to bed until you are ready to fall asleep within a few minutes. We can only hope to achieve this ability without taking extra measures.

My Neurontin (gabapentin) helps my mind relax. Otherwise, it can get started with racing thoughts.

I definitely know how you feel. Sleep has been a big struggle for me for a decade. Oddly, no matter what time I finally fall asleep, I usually still wake naturally between 7 and 8, sometimes just a bit later. I can be up until 3 AM and still wake at 7:45.

My best to you.
