I understand exactly how you feel Horn; I've felt that way far too many times, and I never want to be in that mental state again. Fortunately, in my case, the worst of the shame, remorse and depression only lasts a day or two. I'm also restarting myself, so I can only offer limited advice, but I can offer support if you feel like drinking again. Please post here or PM me if you do.
And I agree with Arpeg's suggestion; take up your wife's offer to join you. It sounds like she can help keep you accountable, and removing alcohol from the house for now is probably a good idea.
