A cup of tea contains a lot less caffeine than a cup of coffee. I drink a lot of
tea in start-stop patterns similar to yours, and I've never noticed the effect
either. But I've known people to stop drinking 6-10 cups of strong coffee a day,
and suffer the symptoms described...

Some people are more sensitive to it, too. I know at least one person who can't
sleep properly for days after having a single cup of tea.

Yes.  I used to drink 3 or 4 coffees, plus over a liter or Coke per day.

Went camping for a week-end, where neither of those were available, and 
had one of the worst non-migraine-related headaches ever.

I've also had cases where i've taken too many coffees, when pulling 
all-nighters at uni, or work, where I would have jitters.  I guess it 
was a combination of being tired and too much caffeine.

Which reminds me of my old .sig file that was a variation of the Mentat 
incantation from the Dune movie that I had found on the Net:

"It is by caffeine alone I set my mind in motion,
it is by the beans of Java that thoughts acquire speed,
the hands acquire shaking, the shaking becomes a warning,
it is by caffeine alone I set my mind in motion."

> Is it just me?

You've probably have not taken enough, or are not atuned to its effects, 
so that even though they're there, you don't notice them (e.g. first 
time pot smokers who don't notice they're high), or attribute them to 
another cause (e.g. I used to think that having the flu made me have 
weird claustrophobic nightmares, except I later found out it was a side 
effect of the pseudoephedrine found in most flu medicine, and not of the 
flu itself).

Yes.  If I drink caffeinated beverages for a few days and then don't, I 
get a really nasty headache.

What’s a headache?
Like Andrew, I have never suffered withdrawal symptoms from caffeine. 
Nor have I had a caffeine rush. I do like a coffee with sugar first 
thing in the morning to “get me going” but no cravings if there is none.

Oh, I think you know what a headache is.  Read a bunch of posts that 
could be answered with "GIYF" and then find a brick wall to bang your 
head against.

That'll surely cause one. ;)

Yeah, some people do not react the same way - which is why with nutrition 
guidelines, a lot of them make no sense at all, because different people 
react differently to things.

Which is why I laugh when I see a new report that says, for example, that 
"high fat diets might just be good for you" - they always miss the "in 
moderation" part.

No, they make perfect sense, as long as you understand them in the 
context that they're /guidelines/ for the statistical norm.  Not a set 
of hard and fast rules for absolutely everybody.

Well, yeah, that's what I was going for.  They make sense for that 
statistical norm, but not for the individual if they don't work for the 
individual.

Not from personal experience.

I would say that that would give you a sore head as opposed to the 
headaches that I have read about. I seem to remember that I did have one 
when I was a child but that is a memory of a memory, now. Very 
occasionally, once every couple of years, I get an ice pick headache 
which lasts less than a second. I don’t think that really counts though 
as they don’t last long enough to have any debilitating effect.
Incidentally, I don’t get hangovers, either. And it is not that I don’t 
drink ;-)

If you don't like the guidelines just wait a couple of years and they 
are bound to change. :-)

My motto is moderation in everything including moderation.

Personally, I think the guideline amounts would be more useful if they 
gave you an ideal /range/ rather than just a single /point/. But who 
cares what I think...

It's pretty easy to get a headache from skipping your caffine if you're used 
to it, yes.

The point to remember is that caffine works by blocking the bits that emit 
the stuff that turns off your brain. (A very technical explanation, yes.) 
However, if you take it long enough, you wind up growing new emitters to 
account for the inefficiency of the ones you already have, so basically your 
body adjusts to it and after a few weeks you're operating at the same level 
you normally would be operating at.

You don't, after a few weeks.
