What is the problem? If you don't wanna go to the party - skip it. And if you want for some reason (maybe there are some of your friends) you still can evade drinking. Of course others will try to pour you some alcohol but you can refuse.
For me it works, in Russia on the New Year, night from Dec 31 to Jan 1, everybody is drinking really a lot - champagne at first, then wine, martini, brandy, whisky, everything that could be found, drinking a lot, then going outside with alcohol, after an hour or two returning home and drinking again even more. Drinking since midnight all night long till morning or even noon. But past two New Year celebrations I'm drinking not more than half a glass of champagne and others around didn't gave a damn.
