Let her be. Sometimes being a friend means not doing what is easy, but doing what is right.
Shakespeare said "True compassion is ruthless". To me that means it is better to call things exactly as they are because then the truth can be faced.
Google Wikipedia "blood alcohol content". Halfway down the page is a chart of what different blood alcohol levels means in terms of physical symptoms.
With a BAC of .30 to .39, here are the physical consequences:
Severe central nervous system depression
Unconsciousness
Death is possible
Problems with:
Bladder function
Breathing
Dysequilibrium
Heart rate
My STBXAH went to the ER in June by ambulance with a BAC of .329
I thought he was dying in the restaurant before the ambulance came, and the people around him thought so too. He went into a coma, but the ER revived him.
He said he wasn't an alcoholic, but I gave him the wikipedia chart so he would know how close to death he was.
As profoundly difficult as it is, I think your AGF's alcoholism is at a very scarey point; my AH got above my pay grade to be able to help.
Best to you in this terrible situation, keep us posted.
