Consider a hypothetical scenerio where Patient T was referred to Psychologist AB for psychotherapy. So,psychologist AB built rapport, took detailed history, went through assessment and finally gave the diagnosis of Alcohal induce disorder. Here psychologist AB started up with hypnotherapy inorder to treat thus following were some major steps:
1) inducing the trance via stair case induction
2) Using Future pacing to get the imagery of future
3) Utalizing urge surfing which is linked with CBT for Substance Use .

Here first Patient was taken to the state of altered attention, higher suggestibility and then future pacing was used alongside urge surfing. You may have seen surfers , moving along the wave so here the scenerio is somehow same. Sympathetic response of nervous system ( increase in appetite , illusions, insomnia , anxiety) is quite similar to wave which moves up and down. So therapist will make him surf over the urge to enhance self control. Urge surfing at subconscious level will help at increasing resilience.
The basic principle is to observe without engaging.
