Swish - try this

Imagine you are sitting in a cinema, seeing a big screen in front of you

Bring up the old image/state , the image of you just before you’re about to smoke

In the corner of the screen see a thumbnail, place the new you image: confident, calm, resourceful, free of the old habit.

Swish:
New image → rushes in big and bright
Old image → falls off the back , crumples, turns black and white

Do this 7 times, each one faster

Finish by imagining the new image in a real future situation.
