When I felt addictions or compulsive behaviour or every-day things were becoming a drag I used to go to a forest for a week or two and live off the land. I only brought clothes and a knife. You find out really quickly what you personal addictions are that way.

Compulsive behaviour can be kept when it is useful, like never forgetting your keys or closing the front door properly, and unlearned when it bothers you.

All in all, I don't mind addictions much, as long as they don't mess with my quality of life. Some addictions seem to enhance that, even. "Addictive expectations", like bricks usually falling downwards and walking usually moving you forwards, those you can't do without, or you would have to rethink everything every time. The The World of Null-A by A. E. van Vogt, an old SF-novel, says some interesting things about that.
