A wise old woman in AA once told me that addicts are just like everybody else, only more so." You will find a full spectrum of introverts to extroverts in Recovery. H I don't think a definition of addictive "personality" is used. Most addicts are using to manage extreme negative internal states. Not everyday bad moods.

I agree with the poster who mentioned Infinite Jest as capturing some of the subjective experience of the "insanity" of an addict.
