Of course this (the OP date) is rather old...
First, to Iamanon... regarding the tylenol and so forth... the Poly is not (and anyone can correct me) a 'dictionary of medical drugs' and consequently unless you are 'knowingly' not telling the truth it should not pick up anything. Doctors may be cognizant of 'drug' definitions but the average person is not. I have taken pain killers that are most definitely 'drugs' (and can be decomposed down to street drugs) and passed all drug questions with flying colors. The applicant (again, I am open to correction) must 'know' that what they are saying is a lie... or have an inkling at least. I have changed all my kids and grandkids diapers and anyone who has done that knows you have to clean up and that means "touch" the child... yet I've never failed any questions pertaining to pedophilia and so forth. I was "deceptive" about something that I "know" from past experience was a deeply emotional and disturbing part of my life... it was destructive to 'me' in finances, in job, in health and so forth and so questions pertaining to that, while I was not at all dishonest, would trigger a physiological "slam" and that is the only reason I can comprehend a 'failure' and a 'lost job.'

I don't think examiners, or at least the majority, are out to hurt applicants but perhaps there is a 'batten down the hatches' syndrome where some feel under attack professionally (at least the underlying science of their profession) and consequently might be a bit less than even professionally affable. But who is to say...

To Liko - as all posts on this site indicate, read the 'The Lie' and learn from it... there is not one guarantee that simply "being honest" will get you a pass. Good luck.
