I can speak to that from my own experience when I was getting out of the military. Granted, it was a few years ago. We used to call it “the death rattle” when troops would be walking down the hallway and they had three or four bottles of pills, of God knows what, in their pockets.
I don't know if it was an individual-based thing or what was going on. However, in having discussions with civilian caretakers and civilian doctors on the other end, when they would hear what we were prescribed, a lot of the times you had to pick their jaws up off the table.
Being in the military is a rough job. Obviously, we contract things like post-traumatic stress disorder, depression, arthritis and degenerative disc disease at a much higher rate and much earlier in our lives than most Canadians do, so that's definitely part of it. However, in having discussions with civilian doctors, they were sometimes taken aback.
