on the drugs thing he speaks to a doctor who advocates the use of methadone, which Brand says is 'a sticking plaster for the soul' (he's advocating therapy) and he manages to be really rather cogent in the face of her patronising behaviour.
in that he is quite clear that he yearns to take drugs again and all the women and shagging etc etc etc counts for nothing by comparison.
i don't really believe this story about the tits, though, i think he's a pretty tortured fellow, personally. not sure whether he is himself a torturer.
