75mg per shot = 450mg caffeine That's a bit over the recommended limit of 400mg a day the Mayo Clinic, FDA, etc. recommend. Not sure it it qualifies as 'enormous' or not.

The amount of caffeine that humans require to live is 0 mg. So ...

Irrelevant to the question (How much is 'enormous'?).

Especially if you like Americanos, chances are you'll be happier with filter coffee from good beans, rather than spending it in an espresso machine. Get an Aeropress, or Hario Switch, or Clever dripper. A kettle and some filters. For beans buy from roasters that do light/meduim roasts, and print a recent roasting date on the package/website. The only expensive item should be a grinder, look at 1zpresso Q/Air/X or Kin…

Not gonna lie, this sounds like way too much work. What I am mostly looking for is some sort of an easy access to a diluted coffee like the Americano, really. I am OK with buying 1-2kg of beans because I am fairly sure that's going to last me 3-6 months. Cleaning the machine I've done in offices -- 3 minute job. But any more commitment just sounds tiring. I am not a coffee connoisseur by any stretch of the imaginatio…

You can get an over-the-cup pour over for ~$10-20, basic blade grinder for the same, and a pack of filters. That’s all you really need.

This style, pour over machine that grinds itself, but uses all water you put in, so it's not fully automatic.

It's automatic enough, but also very cheap. Maybe even ⅒ of a price of a fancy espresso machine. And you can add "too much" water (than the setting you set) to make lighter coffee.

I once quit caffeine cold for 6 months: 2 weeks of pure hell then it was like I never craved it until life got real and stressful and I fell off the wagon. Today, I drink my espresso with a dot of lowfat milk now and life is currently too real and stressful to consider trying to drop it again. I do suspect some of us likely have undiagnosed low-level mood disorders leaving us highly functional but discontent and caff…

I stopped drinking coffee for a month and didn't notice any difference in my anxiety/mood/etc, so I returned to my regular schedule (3-4 large cups in the mornings).

Quitting caffeine after decades of use was a bit of a mixed bag for me in the short term, but positive in the long term. Going caffeine-free made it much easier to lose weight as I have far less cravings for high carbs and sugar now, presumably this is related to the impulsivity impact talked about in the paper. Going caffeine-free also made me very depressed for a while with severe anhedonia, this lasted way longer…

> Going caffeine-free made it much easier to lose weight as I have far less cravings That's surprising to me. In my case one of the reasons I discontinued it (emotional effects aside) was mild but consistent weight loss. The stimulant part of the effect seems to suppress my appetite quite effectively although at least part of that is likely indirect due to sustained task focus leading me to skip meals.

You're not alone, caffeine is a known appetite suppressant.

I second either a moka pot or an AeroPress. The moka pot would be better if you have easy access to cooking facilities (the stainless versions are also easier to clean, and work on induction). The AeroPress would be better if you only have access to hot water.

As written above, coffee from moka pot absolutely destroys me. :( It's too concentrated.

Moka pot coffee is definitely strong. If that's your only coffee maker, I'd just dilute that with more hot water.

An Aeropress is less concentrated in my experience, and it's pretty easy to use. I prefer iced coffee unless it's cold out, so I fill the collector with ice before I brew. The melted water dilutes it nicely, in my opinion.

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

Warning: those photos in the dot-com website are negative images, not the original black-on-white. Lousy with animated ad banners, too. https://ntrs.nasa.gov/api/citations/20100033433/downloads/20... 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…

Thanks for the time capsule. Boy that’s a lot of ads (live video on a computer! Wow!).

The poor marijuana spider tried really hard

Same here, and it made me wonder, why did I go back to drinking coffee?

My best explanation is that there are effects, I just suck at self-awareness :)

Can you speak more to the psychoactive and cognition impacts to you in specifics? Very interested. I am a regular coffee drinker, mostly limited to very early morning (e.g. 5-7 am). Also consume celsius here and there when I want to minimize stomach disruption in the morning (e.g. I am about to run). But have also used THC in the past (no longer, major anxiety inducer for me). Alcohol like so many people. And more re…

I've been a decaf drinker for close to a decade now, maybe my experience is interesting to you: I have better mood, presence of mind and working memory in the morning, especially compared to caffeinated peers. I'm also a lot more aware of when I've woken up from a bad night's sleep (see paragraph 5). I have much less mid-day dysregulation/impulses compared to caffeinated peers. No predictable afternoon slump either –…

I take a 30 min bike ride midday, not a hard ride, just get on the bike and start peddling, I'll now do a leisurely 6-8 mi.

My cognition in my 40s is now better than it was at 26, at 37 before I started this routine I thought my engineering career was over, the post lunch crash, the mental tiredness, just terrible.

The fact that we build our brain work spaces so distant from physical movement is bad for our mental health, our soles, our souls, and doing untold economic damage to our country (the u.s. in my case.), I tried lunch walks for years and it's just too fucking boring, cycling is great, after work I rollerblade and it's so mentally engaging and distinct it obliterates the after work fog.

Funded by the Institute for Scientific Information on Coffee (ISIC) — an industry body — which is a notable conflict of interest the authors disclose but don't extensively discuss

It does not sound like an outcome that big coffee paid for it to be so: Behaviourally, coffee drinkers exhibited greater impulsivity and emotional reactivity, whereas non-coffee drinkers demonstrated better memory performance.

Or, maybe this is the cleaned-up interpretation
