I had same problem few years ago but after installing StayFocusd[1] plugin in chrome I solved this issue. I set allowed time per day to 40 minutes to visit such websites as: reddit, fb, 9gag, youtube. If I need to watch video related to work/studies I use viewpure[2] that way I only watch only that particular video and don't lose my binge time. I also communicate with my friends a lot using fb so I just use messenger website instead of having fb opened directly.
