When taking a polygraph use two methods. The first is the tack, this helps, but you don't have to kill yourself with it. The second involves the tack and mental trickery.....moer mental though, may not even need the damn tack. In the beginning, they ask you some establishing questions, questions which they know the answer too. This develops a base for your body reaction. They will ask you your name, age, sex, addy, things they know. Now, when they ask you these questions, use the tack when answering, or your can just make yourself nervous as hell by thinking about stupid shit like, your girlfriend finding out you fucked that sheep, or thinking about not getting a boner when you are at a orgy. These thoughts will cause your body to give off the nervous, oh shit feeling. Then when they ask you the serious questions, be as calm as possible, think of stupid things like puppies or something, in other words, get in touch with your femanine side. This tactic will allow more lee way for questions to slide. Just try to be as calm as possible when getting asked the huge ones, and then be as jittery as possible when getting asked the established ones. You could always ask for a break after the established ones and then go to the bathroom and take a hand full of valium or vicodin. HAHAHAHA
