Welcome jfreak,
You sound an awful lot like me. I, too, have been able to "function", until recently. My drinking exacerbated some other problems I have had on and off for a while, and even though intellectually I understood that I am an alcoholic, it took my being scared to death to drive (while sober, not drunk) that I finally started asking for help. Stick around. You have found a great group of folks. You might consider checking out an AA meeting, as suggested above. I wish you well.
