I doubt it will work if you simply do it like that tomorrow, but good luck to you; I did do it just like that one day when I gave up smoking, so who knows.
But if I were you I would get into the habit of drinking two large glasses of water after booze (wine) and before bed; yup, you will get up a few times. This will do you good in itself. Then once you get used to and want that water, use it to stop drinking at night if you are tempted to going over whatever limit / amount it is you have decided; for me, it is a full bottle of wine. The water then acts like a trigger mechanism and kills the urge; you just have to fight the urge to forget about it. Then you are set to using water to also help you stop for a month.
Anyway, if you can stop just like that, good for you. It is not a chemical / substance addiction with me, and I know this because of the month off. But those glasses of wine sure help you unwind and make an evening, so to cut that "addiction" out takes a bit of planning. I even have it down to a fine art during summer when the alcohol consumption can easily rise by either a) drinking Lambrusco (yuk), b) drinking spritzers (actually this is the only time I can drink heavy whites as I dislike "Oaky full bodied" white wines), or c) use the same wine glass to drink a glass of water between galsses of wine.
