Polygrapher made it very easy to identify relevant questions vs control.  Did not get a stim test, but did get the lie that chemicals were released when a lie is told.    Advice to anyone taking a polygraph:  Read "the lie behind the lie detector."  Concentrate on controlling breathing, biting your tongue and flexing anal sphincter, instead of the questions.
Also it was helpful to know the order the questions told to you versus the order they are given on the test.  Know what symptomatic and irrelevant questions are and at what point they are going to be asked.  Download all manuals on home page here and go here
