The purpose of this program is to gradually build a life for the addict so they can put something else into that empty glass: a social network, a job, some daily pleasures. If you can do that, it will mean that even as the heroin drains, you are not left totally empty. Over time, as your life has more in it, the glass will contain more and more, so it will take less and less heroin to fill it up. And in the end, there may be enough within you that you feel full without any heroin at all.
