The one I've found that's worked best for me is a Chrome extension called Delayed Gratification that actually only delays my access to the site for 30 seconds. It's enough that I can convince myself to sit there and wait for 30 seconds rather than turn it off when I really want access to the site and feel it's justified.

But 30 seconds is also a decent amount of time to convince myself that I don't really need to see that site right now, and often I'll just close the tab a few seconds in and get on with work.

I've started to use this (Chrome extension): https://chrome.google.com/webstore/detail/strict-pomodoro/cg...

and it as really helped me (serial redditor) be more productive.
