Does Stanhope need a rest?

Stanhope has been out on the front a long long time. He insists that he doesn't need a rest and is always on the go, getting as little sleep as possible. He has had is original squad wiped out completely and obviously seen some horrific things.

He conquers this with alcohol  and he used to have his greatest friend Osborne to help him forgot and carry on. It shows that he drinks alcohol because he is a very short tempered man and he drinks whenever he can.

I personally think he need some time away from the war to recover.
