It won't work. I tried that too at some point. I told my X that we're not bringing alcohol into the house anymore, that we'll both quit (although I never had a problem with drinking), and that we'll only drink outside, if we go to restaurants and such.
At first it seemed to work and she cut down her drinking. Then she started to want to go out and "sit somewhere" with me almost every day (such a nice day! lets go sit somewhere outside and have a drink).
Then, when that wasn't enough, and since I wouldn't have alcohol in the house, she started buying a carton of wine on the way back from work, and downing it in the driveway before she went in. Until she started skipping the whole "going to work" part.
When I asked her: "why did you lie to me? why are you drinking in your car?" she said "because you wouldn't let me drink in the house"...
