This was something I did as well. When I stopped drinking, I didn't get rid of my liquor bill. My liquor bill just became my monthly contribution to my 401k. I figured if I could still manage to pay the bottom line bills and still drink, then I could easily save most of the money. I will admit to buying a new TV. I don't use credit at all; and I couldn't if I wanted to!
It hasn't been all easy, there are unexpected things like lawyers and medical bills. But those are also things I would have neglected when I was drinking. I currently can't drive, so I save a ton of money there too.
