This is a question for primarily caffeine users. I'm currently not interested in "don't do coffee" type answers.

I have a chance to undergo a caffeine detox.

I'm interested in how long do you think I should detox? A week, two or more?

Also, I'm interested in medically backed up answers, not just personal estimations (especially if you haven't done it before).

This is my day 2 off caffeine and I don't seem to have any headaches or severe withdrawal symptoms.

Do you think detoxing every once in a while makes sense? Do you do it - if yes, how often and for how long?

The excellent site has a FAQ about this:

Do I need to cycle caffeine?

There are benefits associated with chronic caffeine consumption, and there are benefits associated with acute caffeine consumption that fade with tolerance; if you like the latter, cycling is mandatory. If you like the former, cycling is not needed.

In particular, adrenaline and dopamine response will be preserved when cycling and respectively diminish or disappear on prolonged use. Adrenaline response is the one that will (presumably) make you more productive.

It doesn't say anything about cycle time but in most people full adaptation takes two weeks so presumably cycle time should be 1-2 weeks.

Personally I wouldn't give up my coffee for a whole week :-).

Note that you can also not drink coffee and instead take pure caffeine tablets, but where's the fun in that? If you go that route you might as well consider nicotine or ephedrine depending on your goals.

Also check out… which explains how it works and claims a 7-12 day reversal period. – w00t Aug 11 '13 at 15:45

I know of no evidence that indicate that an on-off relationship with caffeine would be of any benefit whatsoever. Some people get really severe caffeine withdrawal symptoms which can last for weeks, so if such a person has managed to end caffeine intake, it would be rather unwise to start again, intending to stop at a later time. However, you seem to be unaffected by such problems so it may be that you are able to experiment more.
