Mish,
I'm so glad you found us. You sound like you have done your homework here and you know what needs to happen in order for your brother to get better.
I have had three addicted siblings and the current one is my brother, whom I love. It is very hard, and I'm so glad that I found SR for support.
Sending out hugs to you -- and strength to find your own way, far away from addiction, no matter what happens to your brother.
Love
GL
