I recently was asked to take a polygraph examination to clear my name, and did just that.  However after passing the exam I am now experiencing depression, anticipation and extreme anxity over everything.  While I was in the room after the first round of questions the room literaly felt like it was closing in on me(couldn't have been bigger than an 8x10 room) and the barbaric chair I had to set in seemed like something from a horror film.  When I took the exam I remember I had to sign a waiver but I do not remember the waiver mentioning any possible physical or mental side effects or risks of the machine even though they had to ask medical questions to see if I was 'fit' for it.  Does anyone here know if there have ever been any studies done to see if there are physical/mental health risks or temporary side effects involved in taking a polygraph in a criminal case/investigation?  The whole process has been increadibly stressful for me, any ideas on what I should do now?
