I do wonder if the so-called "addictive personality" is just referring to people whose mid-brains are running amok and calling all the shots. Mine certainly was, in more aspects than just alcohol and opiates.
It was pretty much deciding everything for me without me knowing and I have always considered myself an undisciplined person. Since I've learnt AVRT, with reference to stopping drink and drugs, I have found it useful in other aspects of my life, like diet, exercise and procrastination!!
