I also edit my hosts file to block websites. That's on my main laptop. I have a junk, old, slow laptop that I use for whenever I want no restrictions. 

I think the more unusual and difficult that we find this kind of digital detox, the more we need it.

 Notes on one day of Digital Detox 

I love this. I have a co-worker who has an app on his phone to block him from using Facebook during working hours, and I've also seen people manually edit their Hosts file to block websites, and I like those as small hacks to avoid specific addictions, but truly taking the time for a digital detox (one that lasts this long, as opposed to "I'm going to spend the afternoon reading and offline") is something I want to look into.

Also a big fan of Calibre for loading up my Kindle.
