Ask HN: What do I do about Health Insurance after quitting my job?

As the title states, I'm thinking of leaving my job to pursue my personal projects for 3 months, but my biggest uncertainty and apprehension is health insurance.

I'm pretty lost in this: there's a lot of literature but no clear answer, and I'm not sure what the new regulations are under obamacare...

What's a simple, affordable way to make sure I'm covered?

Thanks!
