thirty-one participants were moderate coffee-drinkers (CD, i.e., people that usually consume between 3 to 5 cups of coffee per day). 3-5 is moderate? To me, 3 is already high. Also, sample size is pretty low and they're all Irish.

This study is Irish, so I think they likely use 170ml cups? That means a normal mug of ~500ml is 3 cups. Perhaps they even use US coffee cup size, which is 118ml? Honestly, using an unit of measurement that varies from 118ml to 250ml in a scientific paper brings the whole paper into question.

I’m Irish.

A NORMAL mug of 500ml??? this is insanity to me

After habitually consuming caffeine (not in coffee form) daily, usually multiple times a day, for more than a decade, a horrible mental health incident happened to me that forced me to stop it for a while. Afterwards I didn't resume the habit, and so I no longer have a tolerance. This has let me evaluate what caffeine does with fresh eyes, so to say, because I can now consume it occasionally while having many non-caf…

Agree, I drink it a lot and then stop drinking it at least once a year for a few weeks, and for sure it's a different mode of mind, but can't really qualify it besides that I remember my thinking being softer, calmer and perhaps even "more correct" without coffee. (But I never had any mental-health incidents, and I drink a lot of it, more than all people that I personally know.)

For many years I go to the same vacation spot (kayaking in the most beautiful nature place I have seen) and go cold-turkey. I didn't notice any side effects of lack of coffee besides slower muddier thinking. After I go back and start drinking coffee, feel back to normal.

I also had a very big life altering mental health incident very recently, drank A LOT of coffee during and I feel it helped, now I am much more calm, "more correct" despite drinking coffee like before.

Based on this I posit that coffee is used by humans to offset unwanted mentality changes, not a cause of unwanted mentality changes.

Okay, you'll definitely have to explain the NORMAL mug of HALF A LITER!

I’m super interested in this sort of study! However, it looks like n=62 here, which I think weakens the results —they’re probably just useful as suggestions of possible effects. Also, any food is expected to have similar effects on the microbiome. They didn’t test caffeine in isolation. In some ways that’s better (I don’t consume caffeine in isolation), but in some ways that’s less useful (it’s possible you get simil…

In 1995, NASA did spiders experiment. Caffeine is a siginificant impulsivity trigger. :) https://rarehistoricalphotos.com/nasa-spiders-drugs-experime...

Don't ask me why some blogger posted the PDF in 2013, and also don't ask me how English Wikipedia editors determined that a Wordpress blog is a "Reliable Secondary Source". I did locate the original on NASA's own website. Public Domain (USGov).

The only good thing that keeps me from collapsing into a state of limbo is coffee and now, even that's bad (seems more like a mixed bag, but still)? Sigh.

Did you know: By replacing your morning coffee with herbal tea, you can remove up to 87% of the little joy you still have left in your life. /s Keep the coffee buddy.

Haha, that was a funny quote!

I've had the same experience. Caffeine is super addicting, the ritual & habits surrounding it is a potent pull. For myself, it makes me erratic, impulsive, more reactive and agitated. One cup a day puts me on edge, makes me sweat more, makes me more intolerant, makes everything feel too slow. It such a sneaky drug and it can really get under your skin without you realizing how much it changes you.

I don't have the same experience, and I drink one cup of coffee (270 ml) almost every day. No agitation, no impulsiveness. I can drink coffee in late evening (let's say 8 pm) and sleep well. I guess I'm trying to say that we should not project our own experience on others, everyone is different.

Does it matter what size the cup is? Usually you get the same amount of coffee water + additional water/milk/whatever.

My prior would rather be that people have wildly varying sensitivity to caffeine genetically. Some get panic attacks, some don't feel much.
