I agree with pretty much all what the others have said - you're lucky, dealing with this in the west, where there are services available to help you detox, doctors who can sign you off sick for a bit while you deal with this, ER's and suchlike.
It's been a challenge for me, to say the least, dealing with this here in Thailand - drinking is definitely part of the lifestyle here, big time, especially among foreigner travellers/backpackers. And alcohol services here are few and far between, whether Thai-speaking or English-speaking (though the support and guidance from the monks of Wat Tam Wua, one of my homes here, has been absolutely invaluable).
So basically - if you've got an ER near-ish to you, get yourself there, tell them the situation and that you need help now.
Right now.
