kajund,
Welcome to SR. I'm sorry for what has brought you here. Know that you are among friends who will share their experience, strength and hope with you, will listen to you and support you.
Have you attended any NarAnon or AlAnon? The face to face meetings were a real life saver for me. I was pissed about going at first, depressed about facing that my son was a drug addict, but in the end they really, really helped.
My son was older by the time I was dealing with his addiction, we did not live together, he was making his own decisions and there was no changing his mind. After about 9 months in homeless shelters, he checked himself into a very short "spin dry" detox/rehab type program and then went to a 6 month recovery house. So, I'm sorry I do not have experience with the type of rehab you are looking into.
I just wanted to say "hi" and wish you good luck.
