It's like there's an entity that takes over my AH and speaks inside his head, telling him that anyone or anything that gets between him and his alcohol is to be gotten out of the way, no matter what.
When this entity gets the better of him, he is very different. He even looks different, the expression on his face, and acts different, the way he speaks and moves.
And he often doesn't remember what he's said or done, later on when the "entity" is quieted and he hasn't had a drink in at least a day. So it seems like possession.
In my experience, when faced with the "entity," I am best served by removing myself from his/its periphery.
