I actually used this tactic to break some habits when I moved. New living place did not trigger the same habits as the prior one, so long as I was careful to not "install" them again...
I experienced this. When I moved, my sloppiness and classiness improved tremendously. However, I've recently started to notice it getting back into its old ways now that I'm more settled. The benefit is that I'm much more aware of it, and am able to recognize it and address it instead of never noticing it to begin with.
