<human>: Condense the text into a few key points

I am a recovering addict. My addictions include alcohol and pornography. I attend 2 different twelve steps meetings for each of these (AA and SAA specifically, if anyone is curious.)  

I have lied to my girlfriend on a few occasions, specifically regarding relapses in my alcohol use, and also about a visit to a strip club and the frequency of my pornography use prior to entering recovery. I have since come clean and told her the painful truth about everything.  

I have not cheated on her with another woman, except for the lap dance I paid for at the strip club.  

She still can't trust me and she wants me to take a polygraph test. I don't blame her - as an addict, lying and deceiving was a way of life for me and I caused immeasurable hurt and pain through my actions.  

In principal, I am willing to do the polygraph if that will ease her mind and help restore trust between us. I'm afraid however because I've never done one before, and I'm worried that I might fail the test. I've done some reading and they're not fool proof, some people say they can easily be beaten.  

Has anybody had experience with such a test? Are my fears irrational?

Thank you for your time.
