You should read The Easy Way to Quit Drinking. I completely think the mentality that "I can NEVER DRINK AGAIN" is the wrong way to go about things. That's like telling an obese person that's trying to diet that they can NEVER HAVE CHOCOLATE AGAIN. Sure, they know a little bit of chocolate won't do much harm, but that can lead to binge eating, etc. etc. If you tell yourself you can never have something again, of course you're going to want it. It's turned into the forbidden fruit. Having that mentality will make you feel tempted and anxious around alcohol.
To me, the important thing to realize is that alcohol is a drug. It's a poison. Yes, it's socially acceptable, but so was using asbestos in buildings. The key is to believe you DON'T want to ever drink again, not that you CAN'T ever drink again.
