I never had intentions when I first stopped of not drinking forever. It was impossible, as far as I was concerned, and I had no desire to do it. I was taught by some good people in AA to keep it at a day at a time, an hour at a time, if necessary. I listened to them, saying always Ill drink tomorrow if I really want to badly enough. 30 years later I still haven't picked up a drink, and haven't had any desire whatsoever to do so for about 29 years. It's a great feeling to be free of the need, and desire to drink. And all ya gotta do is not drink, right now.
I was also 23 when I stopped. Have an awesome life now because I did. I'm certain I'd be dead or institutionalized if I didn't.
