So today i tried to have a whole day at work with no internet, to see if i noticed any difference.
I stopped at 9am, and allowed myself a brief peek for 15 mins at 12.45, but other than that i managed to last the whole day without checking Facebook, Reddit, Here, etc. It was pretty damn hard seeing as i'm sitting in front of my laptop for 8 hours a day, but i did feel that i was able to concentrate on my work for a lot longer and my mind didn't wander off nearly as much. I'm hoping to try it again tomorrow and then hopefully the effect will get better as i go on.
