I never really counted the time I was sober. I know I went more than 10 years once while I was a JW. But I wasn't calculating the time and just figured that out later. While I was fading, I started drinking again a bit. I remember a coworker asking me how long since I had a drink. He figured I was going to answer 12 to 14 years. I said "About 4 months." He was kind of shocked. This losing one's religion while family stays in is kind of depressing and drinking was my coping mechanism.
AA kind of encourages the counting part, but what's most important is today- getting back on that wagon. While it was not wonderful to drink after a year, as long as you didn't stay in the hole at the bottom of your well, you can be okay. Even if you did some damage to your car or you killed someone else in a drunken stupor, you can start being sober again afterward. (I assume you didn't wreck the car or kill someone, so that would be even better.)
Right now, I am somewhere over 2 years sober. That don't mean crap as far as today or tomorrow is concerned. Today, I choose not to drink. I will have to see about tomorrow.
