EA's & PA's are like drug addictions. They actually cause the brain to flooded with dopamine. That's a serious "feel good" chemical. And like all addictions, are very hard to give up. Addicts will lie through their teeth to keep getting that feel good chemical. And remissions are often part of the weaning (sp?) process. The only way to be successfull is no contact/use at all.
