Wikipedia: Caffeine Overdose Symptoms: The symptoms of caffeine intoxication are comparable to the symptoms of overdoses of other
stimulants: they may include restlessness, fidgeting, anxiety, excitement, insomnia, flushing of the face, increased urination, gastrointestinal disturbance, muscle twitching, a rambling flow of thought and speech, irritability,
irregular or rapid heart beat, and
psychomotor agitation.
[66] In cases of much larger overdoses,
mania,
depression, lapses in judgment,
disorientation,
disinhibition, delusions, hallucinations, or psychosis may occur.

It's important to understand that
despite tolerance or a lifetime's experience with a seemingly innocuous stimulant like Caffeine, just like a nicely burning candle if it's put into a bottle of pure oxygen it will burn at its true potential and turn into a blue-flamed torch.
That is the true wonder and beauty of this molecule. It carries enough power to fluidize the body and make it so efficient that just the tiniest dose of a stimulant is enough when before large amounts were needed.
It also means that your innocent-looking cup of tea or coffee or any of the numerous other products to which Caffeine is surreptitiously added - you will have to check ingredient labels - could be a stick of dynamite waiting to go off. It even includes seemingly all-natural things like pure chocolate or cocoa powder.
