Sudoku Addiction

I swear, I can't stop doing sudoku puzzles. I just discovered Web Sudoku, where there are, seriously, billions of puzzles. In four difficulty settings. All fully printable. I do, maybe, six of these a day at work, when I have actual work I should be doing. On days when I'm bored, don't even get me started. I do them on the train. I do them at home when I'm watching TV. I do them when I should be sleeping. I can't stop. It's a fixation. I've become obsessive-compulsive about them. I need a 12-step program, stat.

I'd write more, but I'm in the middle of a really hard one that I've been working on for over an hour, and I'd really like to get back to it. Help me!
