Great question!
I got sober because I was scheduled to have my knee replaced. My T told me that I would have to tell the anesthesiologist how much I drank or I could die while under.
I was too embarrassed to admit how much I drank (I drank absolute and kahluha on the rocks, 2 double shots in a glass of each and was up to 8 drinks a night), so she said, well you have time to cut down before surgery (one month).
Day one: It's my birthday - cut down? Ya right!
Day two: I'm only going to have 2 drinks - at my standard 8 I crawled upstairs to bed with the wisdom

I would start the next night
Day three: Only going to have one drink - - crawling up the stairs again after 6-7.
Day four: March 5, 2004 - woke up and quit cold turkey -went to my first AA meeting.
Still think about it at times but I have my energy source with me every day that keeps me from that first drink.
Tranquility
