The best way to acquire or extinguish a habit is with consistent, salient feedback. noprocrast is a tool that helps to remind and reinforce the user of their desire to not procrastinate. i think adding a captcha to the noprocrast page would make it more useful as it would require more thought than a simple click-through, which is easily habituated as well.
maybe more like google's gmail googles, where you have to solve 5 2-digit math problems in under 60 seconds. but this time, make them really freaking hard.
But, no, I'd just as soon not have override at all.
