The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
We'll talk about the use of caffeine every other day. I know a few habitual caffeine drinkers including myself, just the simple mention of that probably sounds aversive. But there is actually great utility to using caffeine every other day as opposed to every day.

The every-other-day schedule of caffeine intake, to me, seems like the most rational one if one wants to maximize on the performance-enhancing effects of caffeine without suffering the effects of caffeine withdrawal that are associated with being a regular consumer of caffeine and then stopping caffeine intake, such as headache and irritability and so forth.

Another reason why you might want to abstain from caffeine or reduce your caffeine intake for a period of time and then go back to your regular caffeine intake is simply to identify how much of an effect caffeine is really having on your overall level of daily functioning and mood.
What we're talking about is cutting the amount of caffeine that you drink in half for about four days, plus or minus a day, and then taking two days off from caffeine completely. And then going back on that half dose of caffeine indefinitely.
A simpler way to go about all this that still will allow you to get some of the performance-enhancing effects of caffeine and yet experience far less withdrawal would be two things. First of all, just halve your amount of caffeine intake for two or three days. So again, that could be by volume, or it could be by concentration, probably easiest to do by volume. And so instead of drinking an eight ounce coffee in the morning, maybe you do four ounces of regular coffee, four ounces of decaf, or you just have the four ounces of coffee. You do that for three or four days, and then you take perhaps one full day off from caffeine, maybe another full day off.
And then you go back to ingesting caffeine, but you go back to ingesting caffeine at that 50% dose or what used to represent that 50% dose of caffeine for you. And you just continue that way on a daily basis, and then every once in a while, when you want the performance-enhancing effects of caffeine, you go back to what was your original dose, which is now double what you're taking on a daily basis.
