I`v read Allen Carr`s book twice and although it is a valid book, did not made me quit longer than 3 days...
I felt difficult accepting the idea and VOW to NEVER SMOKE AGAIN IN MY LIFE!
It made me PANIC, like you know the feeling at 2 o`clock at night and no smoke at sight?
I think is much easier and approachable to everybody taking
baby steps,
  1. the first 3 minutes,
  2. then an hour,
  3. then a Day at the time
and
Never take another puff!

After 23 Years of nicotine and smoke addiction, I am Finally Breathing Freely and Healing for the last Sixteen Days, 23 Hours and 4 Minutes, while adding 1 Day and 18 Hours to my life expectancy , by avoiding the use of 509 filthy Stinksikarettes and depriving the tobacco company`s and the tax office of 6.874,04 JPY and never felt so good :-)
