I looked at your other posts, and you have been trying for some time to stay sober, with long periods of sobriety and still relapsing. Treatment will do alot for you, and although the money part is a concern, your employer is still supportive! You will be able to manage it, you still have a job waiting for you when you get out, it will all be ok. As long as you keep trying, be honest, and are willing to follow the suggestions everything will turn out ok!
