I have PTSD as long as other thing… I actually wind up beating myself up and sometime my girl{ in my sleep, but not violently ruff} … So Yes I get head ache when i wake up if I don’t take my ptsd me to calm my brain and body down before i go to bed, but when i skip anything i get worse head ache from my own actions as well as my gal with minor bumps.
Try drinking a full 8 ounces of water when you wake up. To absorb it better, put a little pinch of salt in it. There’s science behind this but I am too lazy to look and link right now.
I suggest getting a fitbit. You can set the alarm for whenever, and it has an option to wake you during the best window. When you’re in the best part of your sleep cycle for waking without feeling awful.
