You could try reading Leo Babuta's free 'Focus' book (http://zenhabits.net/focus-book/ http://zenhabits.net/focus-book/). It has all the elements mentioned in other comments here - e.g. Browser blockers and trying to split your time 50/10 etc. I certainly managed to wean myself off Twitter and Facebook from it. I try allowing myself smaller 'pleasures' e.g. The XKCD and the Daily WTF RSS feeds in my email client. Kind of like nicotine patches. Also if you're going to waste you're time it's best to make sure you waste it on sites that are genuinely useful. It's one of the great things of Hacker News that amongst all the time wasting you're acutally learning useful things. So if you're going to time waste make sure its on specific topics that you're genuinely interested in. For one there isn't a bottomless pit of content (as opposed to Twitter) and what you are reading might actually be useful.
