I feel that this is one of the consequences of spending so much time on Social Media sites, that my brain hast just started to look forward to "distractions" when I don't have anything else to do. If I don't have Instagram, I'll open X. If I don't have X, I'll open Reddit, or LinkedIn, or Hacker News. It's hard to get away from this constant need for distractions all the time, and I've found myself to procrastinate on simple things whereas I wouldn't have done that a few years ago.
I'm glad that features like Noprocrast exist. It's unfortunate that other media sites would never implement these features because their business model is entirely driven on people spending more and more time on their sites.
