Thinking about it, the slightly obsessive streak that makes one lock into a habit is precisely the same streak that makes most of us good at what we do. This doesn't help break the habit, though. There aren't solitare self-help groups out there, though. It isn't inherently a destructive behaviour, so you're unlikely to get rid of it in a hurry. Sorry. I'm terribly addictable too. Fortunately I don't have Spider Solitaire on my machine, otherwise my D.Phil. would stand less of a chance than it does already.
