hmmm, THAT is not typical PTSD, per se.
Usually *just* nightmares, hyper-vigilance, detachment. That was about my own level, but it was still pretty bad from an inside perspective.
Had a couple of uncles with more severe service -- one was Bataan Death March, the other WW2, UDT, South Pacific. They would sleep in separate beds from their wives during "crazy" times.
Is he prior service? The VA deals with stuff all day, every day.
As far as the Bigger Jerk with Less A . . . yeah that is heading towards a condition called Dry-Drunk. Like stopping the Self-Medication w/o fixing the "Problem(s)." About where Mrs. Hammer has been hovering around since Rehab.
