Heavy metal helps for me. Try Iron Maiden, Metallica, Dream Theater, Moonspell, Therion, etc. all this works for me. And stop visiting those websites of course ;-). Make accessing them harder, you could add the problematic domains to /etc/hosts to resolve to 127.0.0.1 or something like that.

I'm the opposite, I need silence to focus, I find music distracting!
