If he was that bad yesterday and is now starting withdrawal I would suggest you get him to an ER and let them monitor him through the withdrawal. Tell them how bad he was and that he is asking for help.
Let the medical profession take it from there. They will at least get him through the worst of the detox so he can pick up the phone and call AA or some of his old AA friends or start looking for a treatment program.
Unfortunately, as you probably already know, you cannot get him sober.
I am glad you are reading Co-dependent No More. Have you attended any Alanon meetings yet? They can be a great source of help for you.
Please keep posting and let us know how you are doing, we do care.
Love and (((((to all))))),
