Caffeine, When is it enough?
Every year there are many health warnings, and they often conflict with each other, until the next one comes along. This time apparently four 250ml cups per day is the limit. Well I only have two so I'm right! As for affecting sleep patterns, I find I sleep just as well whether I have a coffee before bed or not. I must be one of the lucky ones. Of course a lucky involving a whole twelve people might be a little biased.

Welcome to the dark side...

This link defines caffeine as "a stimulant which acts on the central nervous system to speed up the messages to and from the brain".

And, "Caffeine is physically addictive, and withdrawal symptoms can include headaches, fatigue, and irritability". I admit, I hate missing my cappuccinos and do get grumpy if I miss them.
What Are Stimulants and What Do They Do?
However, I read somewhere once, that caffeine is not a "stimulant" per say, but rather is a chemical that prevents those parts of the brain from allowing us to sleep; hence the above URL link about the night time impact. So much miss-information I guess...
Anyway, I have a PDF document that I couldn't find how to attached, that is an interesting read if you have not seen it before?
"The complexity of coffee by Ernesto Illy - Scientific American 2002"
Lots of discussion on this subject recently, seems we're all different, some sleep well after coffee, others don't.
FWIW a shot of espresso has less than half the caffeine of a cup of instant.
Does that mean we can up the limit to eight coffees a day
Sleep is overrated
Caffeine is certainly addictive, but that has to be taken in context. If chronic consumption of caffeine is not detrimental to your health or the effects of withdraw are tolerable then being "addicted" isn't much of a problem.
It certainly is a CNS stimulant; it inhibits a neurochemical that inhibits CNS activity. A bit like how if a car is rolling down a hill at 30% braking, cutting the brake lines will make it go faster.
Well, I am addicted to dihydrogen monoxide too and see no harm
PS: Thanks for the context clarification regarding stimulant.
While I do drink some dihydrogen monoxide, I mainly use it to wash in or to make coffee with.
