Black coffee can be good for your heart, studies show

"Caffeine doesn't perk you up, it just keeps you from calming down."

I feel like a little child -- the days are longer, my emotions are a lot richer, when I'm nostalgic, I remember most details, not just the "gist". I'm not mentally "spinning my wheels" and running in circles anymore. It's a little harder to bring myself to do stuff that I don't really want to do, because I'm not running around, looking for stuff to do but am intentional about what I want to be doing.

Energy is unsurprisingly much more stable, it comes from exercise and whole food.

My acne and problems with digestion disappeared.

Expect to be essentially dead for all purposes for the first 7 days.

I'd recommend taking L-Tyrosine (or NALT) during withdrawal, optionally with 5-HTP, it's a natural dopamine precursor and makes the anhedonia much shorter.

I'm 20, coming (cold turkey, usually not recommended) from 2 espressos daily.

I was always irritable, now less-so. I am not sure if that's the coffee's doing, though. A lot has changed since my nine cup a day days.

I drink 1-2 cups in the mornings only, and I haven't seen this at all. How much were you drinking?

It's hard because I also love coffee. I, like you, never had to "acquire" a taste for it- I just liked it.

I've done stints where I'd mix half-decaf and half-regular. I should probably do that again.

I also think teas are a terrible substitute. The closest I came was chicory which is .. an acquired taste.

Will typically drink 2 cups in the morning and an espresso immediately following lunch.

I’ve noticed a big difference. I rarely get jittery unless I’ve drunk no water in the morning.

When researchers say X cups of coffee, they’re entirely relying on their respondents’ personal reporting. So the answer is your best bet is to assume a cup of coffee is about what the average person would call a cup.

I've had espressos in Colombia and Portugal that probably had more caffeine than in a mug of what Americans drink.

So volume doesn't really say much.

I don't know if these things are really 'standardised' at all. Who'd have responsibility to do that?

I disagree. Any good coffee spot that doesn't have the usual coffee franchise branding can do V60 or has batch brew. You would be surprised how many smaller cities even in central/eastern Europe have lively coffee culture. Which city disappointed you?

They have good health effects on nearly everything.

Unfortunately, their content strategy based on truth does not perform very well. More recently they have been picking fights with the pseudoscience crowd and sensationalizing worthless content which can only be a backwards indicator.
