Hi,
I am very sorry that you and your family are going through this time. I am not a medical doctor, so I don't know. Just wanted to send love to you all right now.
Please keep posting. I can hear the worry, desparation, and frustration in your few words. This site is such a great part of our own recovery...This is one of the places where we can learn to love the alcoholic, yet separate our lives from their disease. We learn to vocalize our needs and feelings, and put ourselves first; something that is often times not done because we are so caught up with our alcoholic. We can find serenity here. Also, it is a place where you laugh, cry, and gain understanding and be understood without judgement.
So although I can't offer any guidance for your brother, we all here offer you the invitation to come back. If nothing else, may you go through your day knowing that a community of people are praying with you.
Silver...
