Resisting Urge

I am trying to stop drinking. For 3 days I was able to notice the urge amd not resist nor act on it. On the 4th day, the urge felt so strong that I was resisting….I felt I could not just sit with it ans poured a glass of wine and proceeded to drink 4. Anyway, in retraining your brain, Is it better to resist or react when you cant just sit with urge.
