to me, using cron to disconnect my internet every half an hour just to remind me to break the loop has been immensely helpful. And annoying. But mostly helpful.

My brain switched to offline mode has about three times better focus.

Similarly to this, I'm using my browser in full-screen mode most of the time to eliminate distractions. It was very surprising to me, how big an effect it has, to not see the tabs.

a cron job to disconnect - love it! do you use the break to get up and stretch, too?

Most of the time, yes. But if you wanted a break from PC instead of internet, I can recommend workrave, it's built exactly for this purpose.

Cron job mostly serves to remind me to use internet as a tool, not as something that is constantly on. Building this awareness of how I am using it is immensely helpful.
