Is there a common attitude or emotion when something is trying to detox or quit their addiction? When one person I know is in the process of withdrawing, they are extremely angry and nasty. They are in a constantly horrible mood, barking and angry about everything, they are full of negativity and just very difficult to be around. That behavior continues for a good while, then is only alleviated on the day they start using again. Then they are back to their happy selves. Is everyone different, or is that typical behavior of an addict?
