i'm not heavy drinker, but i've got some friend whom i feel drink too much. they obviously disagree. i see the unnecessary problems that keep popping up in their lives, and i see the connection being their alochol.
i believe if you are serious about quitting your alochol problem you have to meet it head on and join AA, and start on the 12 steps. a lot of people are hesitant to join because they'd rather solve this themselves at home, but you need to bring the problem out in the open and give it a hard go at solving it. a small shot at your ego to solve a problem which is quite large.
i'm looking at stopping alochol myself, but i drink once every couple weeks (sometimes months). my last encounter with alochol was not a favorable one.
