I would suggest face to face as being the most beneficial. You see, part of this deal is to really let someone in...
If they are telling you that it wouldn't work...tell them that you are getting desperate and ask them for help.
Put them on the spot...you will help them more than you know.
If you need the words "I haven't drank for 3 months and I am dying. I think the steps will work for me, but I don't want to do them alone. Will you help me?"
