I quit cold turkey 3 1/2 years ago, but my method requires you to have some major illness. I had major surgery that kept me in the hospital for 10 days, and there, as you may know, the nurses are just unreasonably inflexible about smoking. What with the lines for IV feeding, catheter, NG tube, I couldn't slip away for a puff. No way, even after I could get out of bed. Then when I got out of the hospital, it would have taken a deliberate effort to start again, and it wasn't that hard to avoid making that effort.
