Yeah, it's not so much the money you save on booze, although that helps, it's more the mental clarity you get with sobriety.
After a few months, I started to realize that I kind of treated money the same way I did alcohol, impulsively. I would buy things just to make myself feel better, especially food and clothes.
Now, I'm a real stickler when it comes to dollars and cents. I'm going through a divorce and separation so that's expensive, but otherwise yes, my financially situation is light years better than when I was drinking.
