If you really believe that your W has a problem with alcohol there are several things you can do. First of all, as you probably know, until your W admits she has a problem it will be very difficult for you to help her. (Very equivalent to trying to talk sense to a WAS) Most times, it takes the alcoholic to hit "rock bottom" before they reach out for help. While on the way to reaching rock bottom, the alcoholic and their loved one's lives can be torn apart in every way imaginable. This is something you want to avoid if at all possible. Also, in the process, much of the progress you two have made can be quickly undone.
Secondly, my recommendation would be to find an Al-Anon group and get involved in their meetings. The advice you receive about dealing with this sitch will be invaluable. You may also try and convince your W to attend an open AA meeting with you. This would be a great start as well.
You also have to be concerned with the fragility of your current R at this time. Repairing your M is an enormous emotional drain and adding this additional element into the mix will definitely make you and W's healing process more complex. For many alcoholics, the fear of losing their spouse is not enough of a motivator to address their disease, so I would not recommend that approach.
You have made much progress and I will continue to pray for you that things continue to improve on all fronts.
