Honestly, just delete your Facebook. It’s a better solution and it has the benefit of being officially supported.
It's not so much an addiction as a lifestyle. Telling most people to quit their FB is like telling folks in the US to sell their car and never use a personal vehicle again... they're whole life is structured around that fundamental fact, they can't just leave it behind.
When I deleted mine the second go around I manually deleted and unfollowed everything just in case it comes back. Wish I had known about this extension.
