Oh another thing I wanted to add, maybe the "one day at a time" things is not working enough for you. For now you might need to break that down into smaller chunks. "one hour at a time" or "five minutes at a time"
How about heading off to bed now? It's late in NY! If you are drinking, dump the rest. Get into bed and start this thing tomorrow. Just make it until tomorrow morning without drinking any more.
Tomorrow, get up, have a glass of warm water with lemon. Then make yourself a coffee or tea and hour by hour get through the day. When the evening hits (that seems to be your rough time from what you say) get yourself to a meeting or two, come on here, go for a run or bike ride, anything to distract you. And just pass the hours or minutes without drinking.
