Some people get headaches when they stop taking caffeine. There are lots of
causes of headaches.

Caffeine has many physiological effects, but constricting blood vessels
is not a dominant one. In fact, it is primarily a visodilator, dilating
the coronary, pulmonary, and general systemic blood vessels. The
vasoconstrictor effect is by stimulating the medullary vasomotor center,
but vasodilation predominates with therapeutic doses. Caffeine is also
a CNS and respiratory stimulant, cardiac stimulant, smooth muscle
relaxant, skeletal muscle stimulant, and diuretic. Take your pick.

Wow, that is some explanation. But all I know about caffeine and all I
need to know is that it wakes me up in the morning, comes in tea and
coffee which are both yummy and sometimes when I have a headache, it
makes it go away. ;)

But sometimes it also causes headaches? Isn't that what Sindi was saying?

And if you drink too much of it is bugs your digestive system... I think I
read that it bugs your intestines to have more than the equivalent of a cup
of coffee a day, or something...

...but now is that the caffeine, or just the coffee? Cola and No-Doz don't
do the intestinal thing to me.

Coffee has lots of tannin in it, which tans your insides. Also kills
parasites which helps if you have diarrhea.

So if you have diarreah, drink coffee? Heh.

Well, if you've got the kind that comes from parasites. That's rarer in these
parts than the "just plain sick" kind.

Raspberry leaves also have tannin.

What does tannin do?
Yeah, the parasite thing I'm sure is rare. I know I've never had it (knock
hard on wood).

Soda is very acidic- which is why it messes up the insides so nicely
when one overdoses on it. But I don't know if that's due to caffeine.
Mark- caffeine only really takes 'caffeine withdrawal' headaches away.
(as far as I know) So in that way it causes headaches and makes them
stop. ;)
Carbonated drinks in general can be helpful if someone is having an
asthma attack.
Tannin tanning the insides... something about that isn't sitting right
with me. If I have time I'll look it up.

Tannin coagulates proteins.

It does have a reasonably strong dye-ing action. It's used to tan
leather. It doesn't tan in the same sense that the sun tans your skin,
however.

Soda is acidic but nearly as acidic as your normal stomach digestion
acidity - up to 100X stronger than soda. I wouldn't worry about soda
acidity. Tannin has little action on intact skin but on abraded or burnt
skin it precipiates loose proteins, forming a protective barrier. It does
have an astringent action in the gastrointestinal tract and can cause
constipation (I drink a lot of tea, but am not constipated). However
tannin is a hepatotoxic agent and can cause severe centralobular necrosis
of the liver if absorbed in large amounts. It was once also used to
precipitate some heavy metals, but doesn't work well for arsenic, antimony
or mercury. Currently there are no "legitimate" medical uses for tannin.

Constipation is a cure for diarrhea.

Tannin is also extremely bitter in large amounts, so you would have to
drink a *lot* more than you find in tea to be in any danger.
I find that the carbonation is the most "annoying" part of soda drinks;
that is the part that screws up my digestion if I am not careful.

If you boil it first, the carbonation will be removed. 8^}

It's also then insipid and flat, and much too sweet.

Of course, the carbonation is there in the first place to mask the fact that
it's insipid and much too sweet.
Which is not to say I don't love the stuff.

RE# 65 . . . I think the deal with carbonated beverages and asthma
attacks has to do with the caffeine (though the carbonation may help),
but only tends to work in minor cases.
I was discussing soda with my Dr. today, who advised me to reduce my
soda intake, which is already down significantly (I think so at least),
because too much carbonation sometimes prevents the esophagus (or the
flap at the top of it?) from doing it's job to keep the acid down.
Does anyone have access to that list of uses for coca-cola . . . I've
probably got it somewhere . . . it's amazing, the things you can do
with it.
It's amazing just how much the regular stuff tastes after you've
switched to diet . . . the difference is staggering.
