I did something similar with TV watching. I'm always lamenting the fact that I don't read enough, don't do enough coding side projects, etc. So with the exception of new Mad Men and Community episodes [0], I've cut out TV.

So now whenever I want to watch TV, I just think "what's something else I could do?" Mostly I've filled that time with exercise and reading: a net positive.
