Carl,
Your life is by far not over. Congrats on the 6 months, I'm only on day 11. Your children need you.....even if for now you only get to see them on week-ends. Call them often and stay involved in their lives. Never put them in the middle and just love them, love them, love them. I by no means have the answers about how to get back to sobriety but these people here do. Welcome!!! Julie
