Wow, that is quite a story. It is a miracle he is alive. My wife fell down our basement stairs in 2008 and she had open brain surgery and almost died. That was enough to get her sober, she was in the hospital for 38 days so that helped. She was 39 years old.
Unfortunately she did fall off the wagon 2 1/2 years later and now we are getting divorced. She has been drinking for 2 years straight.
So you just never know what it's going to take, God bless and I wish you all the best.
