I used StayFocusd for a while, and while it helped, I also had the same problem with my phone, resulting in periodic uninstalls of the social apps. I found this to be attacking the symptoms and not the root cause though. I then started using the pomodoro technique, with strict no IM/FB/etc during pomodoros. A nice side benefit of disciplining myself to work in this way was to reduce the impulsive desire to check FB, and over time I noticed that my desire to go onto FB, even when it was "permitted", had been reduced. I don't have StayFocusd or any such plugins installed any longer.
