I use SelfControl for Mac and set the down time to around 15 days. No Youtube no news sites etc. Except HN. It's helped a lot, after a week you can notice measurable change in attention and habit and productivity. SelfControl lets you add 48 hrs to your blocked time repeatedly, so you can get to a 15 day mark pretty easily through repeated mouse clicks.
