Good for you, Big Guy!! An amazing accomplishment. My Dad went through some of what you are talking about, except for the antabuse part, and he's a recovering alcoholic.
He says the urge is always there, but the alternatives to being sober are not worth it any more.
I'm glad I never got addicted and never had to deal with that aspect.
God Bless You, friend!
