Stop or keep going? Urge Surfing meditation advice please.

What is the current advice on urge surfing?

Example: stopping smoking or sugary foods. Do you make a determined decision to stop the behaviour, such as, "right that's my last cigarette or sugary treat" and then surf the urges as they come along or do you just carry on without trying to stop but just being aware of the urges, leaving the possibility of imbibing your substance at a later date?

Thank you folks.
