Hello albionel, Welcome to SR!
Here you are definitely among people who understand.
My sister is a recovering alcoholic and cocaine addict.
My grandmother, grandfather, and step-grandfather were all alcoholics.
My stepson (my reason for searching the internet one night) is an alcoholic and crack addict.
I'm so sorry to hear about your brother. Detoxing from alcohol is a very dangerous thing, but he is in good hands right now!
There is hope for your brother. There is always hope! But he is the one who has to decide that his life has become bad enough for him to change, to find recovery. Only time will tell if this event was enough to get him to want to stop drinking.
You and all who care of this young man will be in my thoughts and prayers.
HG
