How to stop Facebook addiction?

One of my officemates became very addicted with Facebook that he wanted to ask our IT Department to block his access during office hours. To those who seriously want to end Facebook addiction, here are some tips from wikiHow:

1. Admit that you are an FB addict. (Admin: Yes, you have to admit or else stop reading the next steps.)
2. Define your goals of having FB account. If you don't have any goals, skip step #3.
3. Make and follow an FB schedule.
4. Think of other things that you can do. (Admin: You might want to spend your time in blogging, just like what I'm doing now.)
5. Block the time you spend in FB by using parental control sites.
6. Leave facebook. (Admin: Can I just stop reading in step #5? Haha!)
