It's easier to follow a hard-and-fast rule than it is to promise yourself you'll do less of something.
Yes, but it's just a commitment to an instrumental goal. To repeat myself: will it actually change, or will the one fill the void of the other? If you go to a wedding where you are offered a choice between fish and beef, the right ban does force the choice of fish, but most menus are longer than that; in particular, cooking at home offers the longest menu.
