Hi Christopher,
Welcome to SR. I'm Anna, an alcoholic and I've been sober for a few years. In my opinion you have to stop using drugs for yourself. Certainly your wife and child can be a strong motivator for you, in that you want your family life to remain intact. But, ultimately I think you have to want to do it for yourself. I think it's too hard a job to do if you aren't totally motivated.
Read around the board and you'll get lots of opinions.
Love, Anna
