I have a buddy who did a few years in the military, in one of the more stressful specialties. He had an especially damaged sleep habit as well from this.

He went to some sort of "sleep therapist", I forget the exact nomenclature. Anyway, he was recommended a series of tips (from limit screen time to everything else you may see online). He found it did help. That sort of service may be worth looking into.
