Very pleased with the result!
It was a lot of back-to-backs; tiring by the end . . . but ultimately rewarding as I got the good news a few days later.
I used some hypnotic phenomena, to show that their subconscious was onboard, and they all smiled at the fact their deeper mind can control their physiology. The induction and deepeners were quick but well received. Then I threw all I had at the habit they wanted shot of.
All five—done with smoking.
Feels good for all involved.
