For me, the greatest thing was the absolute FREEDOM I have now. I used to not go anywhere in the evening because I'd start drinking right after work, and I didn't want to drive drunk (not that that ALWAYS stopped me). I can do what I want, I do not have to think about how I am going to try to "manage" my drinking. I feel better physically and mentally.
Honestly, as much as I LOVED to drink, there is not one single thing I miss about it. It takes getting used to, living without drinking. But it is SO worth it.
Imagine how you would feel if your husband had chest pains, or one of your kids had an accident or became terribly ill and you were too drunk to deal with it? Those things can happen.
It's great to just be PRESENT all the time.
