What kind of booze? Beer or liquor? I can speak for beer. I've switched to light beer and I love it and refuse to give it up. I'll have maybe 1 or 2 a week now, and only when I really really want one. I don't think it's necessary to give up light beers as long as your tracking it.
As far a liquor, I just have a natural tendency to not crave it. The last time I had a gin and tonic was about 6 months ago. Although I could have one any day now, just for the hell of it.
