Caffeine is the most widely consumed stimulant to counter the effects of sleep loss on neurobehavioral performance. However, to be safe and most effective, it must be consumed at the right time and in the right amount. This study proposed an automated optimization algorithm to identify safe and effective caffeine-dosing strategies that maximize alertness under any sleep-loss condition.
"We found that by using our algorithm, which determines when and how much caffeine a subject should consume, we can improve alertness by up to 64 percent, while consuming the same total amount of caffeine," said principal investigator and senior author Jaques Reifman, PhD. "Alternatively, a subject can reduce caffeine consumption by up to 65 percent and still achieve equivalent improvements in alertness."
[...] The algorithm was assessed by computing and comparing dosing strategies for four previously published experimental studies of sleep loss. For each study, two dosing strategies were computed -- one which enhanced the predicted PVT performance using the same total amount of caffeine as in the original studies, and another which achieved an equivalent level of performance as in the original studies using a lower amount of caffeine.

Not really, one of the things that caffeine does is it messes with the blood circulation in the brain, which is why you often times see it in over the counter remedies for migraines. You're body also gets used to the caffeine's impact on your body clock, which can have it's own serious issues if you're counting on being properly awake for things like driving.
This whole business about being able to cut down to that extent over such a short period of time is dangerous advice and people really should be tapering down to allow their body to get used to the effects of lessened caffeine intake. Any time you're taking something in that quantity that's meant to affect the brain, you should be tapering down.
Like I said, it's dangerous advice, that's a relatively large amount of caffeine over a long period of time.

Yeah, we've heard you twice. And still not a shred of evidence.
Most people can go from constant cup on the desktop to nothing at all on the weekend or on vacation with zero problem.
You're making claims like coffee is crack cocaine or something.
Coffee is a habit, not an addiction.

No, you are mistaken. I've always had this sig.

Yeah, I'd go on vacation and drink maybe 2-3 cups a day with no issues. Going cold turkey? Only thing I noticed was my Mr Coffee getting dusty.
My ducks are not in a row. I don't know where some of them are, and I'm pretty sure one of them is a turkey.
