I go through phases where I feel really productive, and at other times I feel useless, and have a hard time stepping away from the TV or computer. But ya, I usually feel good after cleaning up the house, because thats when you can sit back and really enjoy and appreciate that you aren't a slob, which is what I am when I drink.
I think a lot of it is, when you stop drinking, you start regaining your self-esteem and you take care of yourself and the things that are yours. For a lot of us, when we are drinking, that all goes out the window and all that matters is getting drunk. I remember being on binges and looking at all the empties and thinking who cares. Sober people care, drunk people not so much haha
