Flag your Facebook account for permanent deletion and then go on a two week vacation without your computer or phone. By the time you get back, you'll be over the hump of needing a social media hit, and your list of Facebook friends will be gone, which is a good barrier to re-entry. Same for Twitter. Getting rid of Reddit, HN, etc might be harder, but if your habits haven't changed after two weeks, you could also set up a hosts file to block problem sites before your vacation.
