I would disagree. It's not evil, but neither is it what you suggested.
A certain amount of caffeine has been shown to have a beneficial
effect on muscle stimulation during exercise - so much so that I know
some Olympic level trainers suggesting that a cup of coffee before
working out is not a bad thing. However, it's also a diuretic - which
for most people is an issue without compensating intake of additional
water.

Agreed.

The "diuretic" myth is probably one of the biggest fallacies about
coffee. The logic goes like this: Diuretics cause dehydration. Caffeine
is a diuretic. Coffee contains caffeine. Hence drinking coffee causes
dehydration. The flaw in this logic is that coffee is NOT mostly
caffeine, it is mostly water. The water provides hydration, while the
small amount of caffeine has negligible or no effect. Even weak
alcoholic beverages like beer don't cause dehydration as the amount of
water is so great that the small amount of alcohol doesn't increase
urination all that much (I know the old storing of renting beer, not
buying it).

"Investigations comparing caffeine (100-680 mg) to water or placebo
seldom found a statistical difference in urine volume. In the 10 studies
reviewed, consumption of a CB resulted in 0-84% retention of the initial
volume ingested, whereas consumption of water resulted in 0-81% retention."
See "http://www.ncbi.nlm.nih.gov/pubmed/12187618?dopt=Abstract"

However the benefits of coffee go far beyond the beneficial effects of
the caffeine on performance. Coffee has been shown to have beneficial
effects for preventing Alzheimer's, mitigating asthma and apnea,
preventing many types of cancer, preventing diabetes, preventing
Parkinsons, headaches, kidney stones, gallstones, skin cancer, obesity
and impotence. Remember, coffee is an herbal beverage, made from the
seeds of the coffee plant. I remember hearing Dr. Dean Edell saying that
if coffee were newly discovered, it would be hailed as a wonder drug.

Eh? What's a hangover then? What's the standard preemptive tactic?

as I understand it, the classic hangover is caused by the effects of
aldehydes on the brain. The pitcher of water thing may work simply
because if you're waking up to piss 3x during the night, you're flushing
out all the toxins as fast as your kidneys can filter them.

Of course, if you have a weasel-like super-metabolism, you generally
sleep right through the worst of the hangover and wake up in the morning
craving bacon, fried potatoes, and coffee. Or so I've heard.

Dehydration is the biggie - even beer will leave you dehydrated as normally
you'll piss more than you drink.

The poison is in the dose. The amount of water in the beer
is irrelevant. Alcohol interferes with the action
of ADH (antidiuretic hormone) on the kidney.
As long as EtOH is in the system
the kidneys pass more water than they normally would,
changing the ionic balance in tissue and fluids.

This is not true.

The Encyclopaedia of Sports Medicine states that in a test of 0% alcohol
fluid, 59% of the fluid was retained after six hours, while for 4%
alcohol, 40% of the fluid was retained (4% alcohol content is typical
for non-light beer). You're falling for the same myth of dehydration
that many people believe is true for coffee too, though at least for
alcoholic beverages it's true that a lower percentage of it is retained
than for non-alcoholic beverages.

The problem with beer is that it doesn't contain enough electrolytes for
proper rehydration, and the Encyclopaedia of Sports Medicine warns
that even light beer has this problem.

Right, but some people apparently believe that the more beer you drink,
the more dehydrated you become. This isn't true. You retain less of the
fluids than for non-alcoholic beverages (40% versus 59%) for the reasons
that you state. But it's not a net negative.

It's true. I think Hunrobe observed it about himself here before, but
occasionally I have also gone for days on end without taking in any
liquids other than those with caffeine or alcohol in them. It may not
be a healthful equilibrium befitting an Olympian, but neither did it
result in me dehydrating myself into an uncomfortable state.

I think I'll have another beer.

What happens is people get confused about coffee versus caffeine, and
beer (or wine) versus alcohol.

Make it a Guinness.
