No. I'm around 0-2 cups a day and am starting to worry about addiction. I was able to get through days with no coffee intake but now I'm sleepy without it.

I was a nice boost but now my baseline has shifted.

Leaving asides the heavy variability in metabolism rates of caffeine... yea I've been up to 18, at which point my most major water intake really was coffee... Not saying mine was healthy, more saying studies show variability in how much coffee is healthy per person.

As far as I'm aware the best meta-analysis shows that life expectancy peaks somewhere between 2 to 4 cups per day.

It would be crazy to think that that's strictly causal but I think it does show that people who care about their health can drink 3 cups a day happily.

I'm at 4-6 a day, which I don't consider to be an outrageous amount, at least I don't think I drink 'a lot of coffee'.

But I'm not kidding myself, I'm an addict. Not drinking any in the weekend causes pretty bad headaches.

Coffee to me gives the perfect "drug ambience": definitely there but easy to ignore... Pretty complicated stuff.

I was drinking 10 a day when someone offered me "Java" coffee. Oh my days. Pale, shaky, heart palpitations. I couldn't touch coffee for almost a year after that mug.

Apparently, you're supposed to drink it in teensy cups.

Who knew.

Finland average coffee consumption is almost 3 cups a day per person, but that's a bit misleading statistic because it includes children too, who in general don't drink the stuff.

Yes, but I'm Swedish.

The average here seems to be around 3 cups per day (or ~9 kg roasted coffee beans per person and year, haven't computed the cup size that renders).

Perhaps its the actual measurement cup vs a big mug cup.
