For best results, a person taking a polygraph should be well-rested and free of
any extraordinary fatigue or stress factors on the day of the exam. This
means getting a good night's rest, eating normally, and avoiding stressful incidents
(arguments, interrogations, emergencies) prior to the exam. If the person
is in any pain, we suggest postponing the exam until the cause of the pain has
been remedied rather than attempting to control the pain with medication.
If the person is taking regular prescription medications he/she should continue
taking those medications. If the prescription medications are taken infrequently
"as needed" then we generally advise not to take these medications until
after the exam. It is ok to take aspirin or other mild over-the-counter
medications, which should have no affect on the exam. It is normal to be
concerned about the exam and a certain amount of nervousness will be expected
by the examiner.
