Quitting smoking was without a doubt the hardest thing I've ever done (18 years ago) - these are great strategies! Although I admit, seeing it all down on a list makes it look quite daunting! (Hint: it is, but it's doable.) But then, sometimes my Mind Sweeps look pretty daunting too! Getting it all down on paper, y'know...!
"Unfortunately" I had no chance to experience it myself - both smoking and quitting smoking.
