Hi Janis
I am sorry I can't help with a doctor, as I am in Europe, but I think you will find that most (some?) doctors will prescribe Revia/Naltrexone for abstinance (Although trials show it does not work for abstinance).
You can just say you have a friend who has been taking it and it has worked very well for her (You actually have- it is me:)) and you would like to try it.
You can 'fess up at a later date when you have your drinking under control, but at this stage the important thing is just to get it.
I went to a doctor who I have never been to previously and told him I wanted it for abstinance and got it no problem- the problems seem to start when you tell them you are planning to drink with it.
Wishing you luck, hopefully someone else will be around later who can help with a doctor in your area.
And Welcome to the board
