If you think you have a problem with porn, you probably feel alone--a lot of people would laugh if you say you are addicted to porn. Viewing porn is just normal behavior, right? If you feel like porn is tearing apart your life, then it's not normal behavior--it's a problem that you need to fix, and this book can help. Addiction isn't just a habit or a behavioral choice. All forms of addiction, including addiction to pornography, bring about changes in the brain that make it increasingly difficult to stop using. The brain's reward system, which is activated by pleasant or exciting stimuli, releases dopamine during porn use. Dopamine is a neurotransmitter that helps carry nerve signals across a synapse. When it is activated, dopamine enables generalized feelings of well-being and satisfaction that can make porn users experience feelings similar to a drug user's high.
