Re:Too much coffee: Caffeine overdose and drowning (Score:5, Informative)
89.6 cups is a lot of volume so it is unlikely that one could drink that much at once. The question posed was whether 100 cups in 24 hours would be fatal. Since the metabolic half life of caffeine is 4 hours, this problem becomes a little more complicated. Assuming the 100 cups were spaced evenly throughout the 24 hour period (one each 14.4 minutes), we can calculate the total caffeine in the bloodstream at any time durring the 24 hour period.
At one cup every 15 minutes, the level of caffeine reaches an equilibrium with the rate of degredation arround cup #70 with a blood level of 2.4g -- much less than the LD50 of 13.4g. Even if you were drinking a cup every 5 minutes, the blood level would stabalize around 7.2g -- in the danger zone but still likely survivable especially with medical attention.
Caffeine is a dierettic (makes you pee) and so your biggest risk would likely be dehydration. But that's another story entierly.

No, coffee isn't dehydrating because it contains too many electrolytes. It's dehydrating because caffeine is a diuretic, i.e. a drug that induces urination. In any case, though, the comment about serving with a glass of water points out something important- that you can theoretically overcome issues with overhydration/dehydration/mineral depletion/etc. by drinking something else or taking electrolytes at over the same time period that you're taking the coffee, negating its negative effects (other than the potential caffeine toxicity).

Caffeine is a stimulant to the nervous system and increases the blood pressure by causing the injection of adrenaline, which in turn increases breath and heart frequency, thus bettering the nutrition of the body and making you feel awake and alert.
But caffeine is not the single ingredient of coffee. Coffee contains about 700-2500 different ingredients (The different sources give different numbers). Many of them are created during the roasting process, and the way the coffee beans are roasted thus strongly influences the later taste of the coffee. Many of those ingredients are solulable in water, thus increasing the electrolyte side of the balance.

Symptoms of DHMO ingestion include sweating and urination, and possibly a bloated feeling, nausea, vomiting and body electrolyte imbalance.
For those who have become dependent, DHMO withdrawal means certain death.
Dihydrogen monoxide is also known as hydroxyl acid, and is the major component of acid rain. It has been found that malignant cancer cells only develop in its presence.
The American government has refused to ban the production, distribution, or use of this damaging chemical due to its "importance to the economic health of this nation.".

As dosage increases however, psychological effects such as paranoia and anxiety are common, and panic attacks are often induced (it's happened to me).
