Mortified,

I'm glad that I can at least give you a little more courage with my experience.  It was hard for me to beleive that countermeasures would work, since I could count with one hand how many people had posted their success stories here.

Till the last minute in the waiting room, I was nervous as hell.
I think it is only human nature to feel that way.  The thing that made me the most nervous was the fact that this would be the last time I would apply with a LE agency.  If I did not pass this test, I was going to throw the towel in.  [ Just as a side note, I have nothing in my backgound that would disqualify me from being in LE, I was never a trouble maker.  It was hard for my wife and people who know me to understand why I couldn't pass a "Lie detector Test".  I think that some of my friends maybe even changed their perspective about me, since in our culture we have blind faith in those tests]

I beleive that if you practice, you can beat this test as I have.  As far as Doug William's manual, In my opinion you have already learned all there is to know.  

Good Luck!
