I'm relatively new here, so I can't offer any great advice. I can tell you that my wife started drinking many years ago, and seemed to control it fairly well until about two years ago. She started with beer, and for a long time, that was all she ever drank. It didn't really seem to affect her that badly. At some point she started buying hard liquor, and was drinking it two or three times a week. Unlike the beer, the hard stuff turns her into a zombie. She gets to the point that she can't walk, and falls frequently.
Her drinking has accelerated this year to the point that she's drunk three or four nights a week. Two weeks ago, she fell and broke her ankle while drunk.
With any luck, your wife will be able to control her drinking. However, from what I've read, drinking in the morning and hiding it are both signs of a problem.
I hope you guys can work it out.
