I simply use an app called Hosts Editor on my phone to map reddit.com to localhost. This instantly broke a habit I had of wasting time on reddit (an activity I generally regret after the fact, but that I still tended to do whenever I had a few spare minutes) and increased the time I spent on reading more interesting content (instapaper, or books). No downsides I have noticed.
