Don't read reddit. Or at least read very little.
I have very few news sites in the folder I "open all in tabs" every morning: Google News, /. (I'm nostalgic, it's not terribly useful), HN (via hckrnews.com with Link Visitor to mark as read), and reddit.com/r/science (plus Environment Canada, Michael Geist, and XKCD).
I check those most mornings, then check /. and hckrnews a few times a day.
Sometimes I want more, but I've learned to resist that want. Between HN and Google News, I encounter most of the things I need to know. And, of course, I see news stories in my FB feed, shared by friends, mostly dross, but some few nuggets.
And I never go beyond the first page of any of those (except /., I tend to work back to the last story seen, but that takes very little time).
Imperfect heuristic for validating the I encounter most of the things I need to know statement: Never, not once, has my life been affected in any meaningful way by a story with which I was unfamiliar, I have rarely been surprised professionally by unfamiliar news (I am a security consultant) and never with any impact (interesting, I will look that up and get back to you).
We are all here likely to be voracious readers, curious beyond measure. We. Do. Not. Need. To. Know. Everything. Your brain is likely already full.
As someone else mentioned, willpower helps too, and if you don't have willpower, get a hobby you like, and then start examining how much of your hobby time you spend reading news that has little/no impact on your life.
Note: I have never used RSS, have a twitter account but hardly ever go there, rarely listen to radio news and never watch TV news. I do not seek to optimize the amount of information I consume, I seek for and seem to have found "pretty darned good enough".
