Can you find a project to occupy yourself with, so you can fixate on what you're doing instead of what you're not doing? Could be anything, clean the house, build a model car, read a book, play a musical instrument, anything that takes your mind away and gives you craving relief.
I personally didn't have a problem with my first sober New Year's Eve, since I was still in bad detox and shaking and vomiting and hallucinating. But even the years before, it wasn't a big night for me, and I viewed it as "amateur night" - a great night to do what I would normally do anyways, drink a lot of alcohol, while staying home and avoiding trouble and police.
