coding reference, wikipedia, blog writing, foursquare, skype, one hour HN every day... that's hardly what we can call an Internet diet.
What about taking some holidays with no Internet at all? Like 2 or 3 weeks hiking in some remote area - it takes a few days to stop thinking about checking emails, twitter, HN etc.
Bring a notebook and take notes about your ideas. Hiking works wonders for that, you'll get tons of ideas in a day hike.
Back when my laptop wasn't the size of a fully grown hippo, I used to take day-long train trips with it. Lacking a phone to tether it to meant I had nothing else to do but working and coding. Rarely have I been as productive as during those trips.
