For some people, that approach may work. If it does work, it's great since it avoids the mental anguish of beating yourself up (which is damaging in it's own right). That said, I can see two scenarios where it won't work: (a) those who have been dealing with the problem for an extended period of time, and (b) those who replace one counter productive habit with another. At the end of the day, we must face the reality that these products are designed to gain and hold people's attention. They are intended to be psychologically difficult to escape from.
