I read the book several times, probably about 10.  I practiced breathing and answering the questions I knew they would ask about the incident carefully monitoring my breathing.  I used the pausing the breathing, butt constriction, and some horrible thoughts of getting caught when the control questions were told.  I passed with flying colors.  This method DOES work but you need to be prepared and well practiced.  Don't think you can just read the stuff once and youll be fine.  You need to gain a level of confidence about the process.  If you are someone who is going to panic, I would not recommend this.  But if you can be cool under pressure and you prep because you need to win, this is the way to do it.  I told myself if this works out, I would take the time to come back here and say thanks...  Mine was a license restoration from the sec of state... needed further evidence...  private examiner who claimed to have worked 30 years as a polygrapher for the police with 1000's of completed polygraphs...  No matter, it was my first time and I had the edge because I knew what we BOTH were going to do...  Thanks guy!

Congratulation. I am taking my test soon. Very soon. What is the book you have read several times? 
What kind of questions did they ask about your private life? sex and so on?
