Planning: Determine in advance what you will consume and when.
Support: Find others like you that you can use for support (just not on Twitter ;).
Self-empowerment: 12-steps call this your "higher power", but I think that brings too many religious overtones (even though they explicitly say it's not meant to). Regardless, there is a power we have (or are given, if you are religious), but you have to dig for it. The journey is what provides the power.
Good luck!
You are in a different boat. You physically can abstain forever, but your career doesn't allow you to. I could see how abstaining would be a very helpful option there.
>I wish the term gave more clues as to its meaning. Dozens of diets are about intentionally restricting foods for health reasons. Veganism doesn't have a monopoly on dietary restriction. Nor does it imply avoiding processed foods or additives. In fact, several other diets have those guidelines baked right into their core philosophies (e.g. raw diets). You're probably too invested at this point, but I think "infoforager" would be more indicative of the meaning here (carrying a lot less baggage too, but perhaps that is a disadvantage for you).

>Once that basic idea — that in the timeline of human history and pre-history we simply haven’t had time to adapt to our new circumstances — took root in my brain it seemed natural to apply it to other domains besides food.
Indeed, it's an incredibly powerful and flexible idea (exhibit A: http://www.paulgraham.com/addiction.html)! Unfortunately, many circles (e.g. skeptical community) will dismiss it out of hand because it smells like the naturalistic fallacy... also because skeptics tend to treat anything other than unquestioning embrace of new technologies as anti-science.
Personally, in the last year I've drastically cut back on my time online and upped the time spent in the real world, whether visiting with friends & family, playing pool at the pub down the street, biking in the city, whatever. It's a much more immediate, and in many ways richer, source of information than Twitter, Facebook, etc. Oh, and I've gone back to a feature phone from a smartphone after realizing it was basically a shiny tracking device in my pocket with an expensive monthly upkeep ;-)
I've got to work out a plan to deal with it productively. It's important and necessary, but carries a high potential for inefficiency if not managed well.
