Yes, absolutely. The urge to juuuuust give Facebook a quick check is there, it's muscle memory almost, and it takes a conscious effort to break it.

I uninstalled the FB app ages ago, and I've removed all shortcuts to FB from the start pages in my browsers. That helps a bit. I've also set Cookie Autodelete to not allow any FB cookies, so I have to log in every time, presenting a further small hurdle I have to cross. It's a very small thing, but it makes me more aware of what I'm doing, so I can stop myself.
