I agree with your assumptions driftwood...I'm addicted to being addicted. I'm always all or nothing...I find moderation incredibly boring. Many people have told me this about myself as well so it's not just me thinking I am this way. When I don't drink/toke or smoke to access I always end up getting addicting to other things...exercise, diet and nutrition, playing guitar for hours on end...video games...reading etc. When I get interested in something I tend to focus solely on that to the exclusion of almost everything else...I become fascinated by it and need to know everything about it...but I always, invariably, become bored with it and move onto something else. Good theory.
