Jim, not sure what to say really except if this right now is not a threat to your own sobriety then it all boils down to is your love for her enough to where on occassion you can accept this or not?
My wife had a drink last week when we were out to dinner, no big deal at all, I have not seen her smashed in probably 10 years, but I was still drinking them so I really did not care about it. She does not keep booze in the house, but as little as she drinks it would be a waste of time any how.
If she got really smashed how would I react? Heck I do not know, probably just move on, now if she started to get smashed all the time perhaps we would have a talk, but to be honest I doubt very seriously that would happen, we have been together for 18 years and in that time she may have drank as much as what I used to drink in a month! LOL
