Hey L&D.
I'd suggest trying to get to a meeting today, and also making use of the AA speaker recordings between time if you feel those thoughts of drinking or self-pity creeping in. There are literally thousands to choose from. There are some on YouTube, but i find this site better..

You know, when we are sober there are so many things that we CAN do that we couldn't before. Try to focus on those things rather than on the one thing that is removed as an option in sobriety.
When you go to today's meeting try to get some numbers of folk who will be available to take a call later this evening if a touch base would help - even if you just call to say "I'm still sober. Happy New Year".
So, what have you and your girlfriend decided to do tonight?
