And for the lyric "I ain't the dog that bites the hand that feeds me", I think that Steven is saying that the fans are "the hand that feed" because they buy their albums, go to concerts etc. And "bites the..." means he doesn't want to disappoint the fans. He wants to stop usig drugs so he could be healthier and "be there" for the fans. I guess it makes some sense.
