I regularly stop drinking caffeine for days at a time and have been unable to notice a difference. It's a shame because I was really hoping to find that my headaches had an easy solution like not drinking caffeine, but they don't appear to be correlated.

How many days at a time? I used to drink a lot of coffee on weekdays but none on weekends and didn't notice it making any difference. Stopped drinking coffee altogether and after a few days I was really noticing the difference, and it took about two weeks for the withdrawals to wear off.

Six weeks, once (mostly to prove it for conversations like this), more often something like 2-6 days. I can really take it or leave it as caffeine, but keep drinking stuff for flavor and enjoyment - if they made decaf red bull I could give up caffeine tomorrow :)

Fair enough, it does seem like different people react to it in sometimes markedly different ways so I don't disbelieve you.

(As an aside, it's an interesting problem how long is 'long enough' when proving you can go without something.)

I find it necessary to stop caffeine for 14+ days before I get to experience improved energy levels. For about 1-2 days i feel really tired after discontinuing coffee, then for the next couple weeks I feel OK but not as good as when I was drinking coffee. After a couple weeks I start feeling like I have more energy than when I’m drinking coffee daily.

I still choose to drink coffee just because I love the taste and the ritual so much. I limit myself to 1 cup in the morning daily.
