CBP pre employment polygraph coming up NEED tips

[KingofD]

Good morning I have a cbp pre employment polygraph coming up and I need your insights and tips on a few things
First off I'd like to state that as far as answering the cbp polygraph questions found on AP I am being completely truthful . Just don't want to be falsely labeled deceptive.
I am no stranger to polygraph testing.  I've taken one in the past that was a dry run and it was about sex and dating. Lied and still passed . There were no stakes ..I purchased Doug Williams manual and I read the APs lie behind the lie detector.  Just a few pointers I need .
When do you start showing a reaction to a control question. Is it the moment you recognize it as control.or wait for the examiner to finish
Also how can I use the count back method .
I should be hopefully calm on the relevant questions
. I also used an over the counter supplement called CALM In my previous polygraph. Will it help ..
