Welcome. Hang out on the forum and visit some of the other sub-forums. There's lots of info and support. I've been a heavy drinker for 15+ years, been trying to quit the last five. I am a week sober today. I've had longer stints in the past. My advice is to read about recovery plans. My biggest mistakes was thinking I was above such things and I would just wing it. When the rubber hit the road, I caved.
Check out the Alcohol forum, lots of great people there and many folks that would be considered "veterans" to sobriety.
