CNN.com has a 12 step plan listed for email addiction.  Oddly enough, one of the steps is not throwing away the Blackberry Crackberry.  So go get started, and don’t fall off the wagon.

1. Admit that e-mail is managing you. Let go of your need to check e-mail every ten minutes.
2. Commit to keeping your inbox empty.
3. Create files where you can put inbox material that needs to be acted on.
4. Make broad headings for your filing system so that you have to spend less time looking for filed material.
5. Deal immediately with any e-mail that can be handled in two minutes or less but create a file for mails that will take longer.
6. Set a target date to empty your in box. Don’t spend more than an hour at a time doing it.
7. Turn off automatic send/receive.
8. Establish regular times to review your e-mail.
9. Involve others in conquering your addiction.
10. Reduce the amount of e-mail you receive.
11. Save time by using only one subject per e-mail; delete extra comments from forwarded e-mail, and make the subject line detailed.
12. Celebrate taking a new approach to e-mail.
