If it’s coffee/tea, how do you take it? I typically end up consuming 200-400 Mg a day depending on if I go to the gym or work overnight. I either do black coffee (iced ideally) or sugar free redbull/monster. I’m considering switching to caffeine pills but I know it wont scratch that habitual itch of drinking it down.
I detest coffee. My caffeine intake is wholly sodas, specifically Coke Zero. It only has 34mg per 12oz, so I don’t get a lot of caffeine every day.
I’m not a medical professional, this is not medical advice.
So there are factors to consider; the strength of the dosage and the frequency at which it’s being consumed. Additionally if there are rest cycles.
The positive effects of caffeine are significantly reduced by the frequency it’s consumed. This can lead the user to consume more to reach their desired experience.
The negative effects however are capable of stacking. Such as its impact on blood pressure and one’s capacity to regulate emotions. Caffeine is also a poor stimulate for someone who is already fatigued or is experiencing weakened attention. It’s best at maintaining ones current level of awareness and fatigue.
One could be accidentally poisoning themselves with vitamins or other additives before caffeine becomes the concern.
It’s generally accepted that 400mg of caffeine in a 24 hour period for a healthy individual is the maximum dosage.
To avoid a dependency on caffeine and to experience its positive effects at regular dosages. It’s best to practice moderation only by consuming it rarely.
Many people will find this unreasonable. The next best option is to practice rest cycles of equivalent proportions. Such as 2 days on, 2 days off. Going larger than that invites negative effects such as withdrawal and tolerance forming.
Everyone is unique, I’m not trying to write a scientific paper. I invite everyone to scrutinize this information and consult with qualified professionals about their own health before following through with information on the Internet. Addiction in all its forms is a serious matter and deserves respect.
I drink three cups of coffee a day, first thing in the morning. If there is caffeine in something else I consume I am ignorant of it.
Ideal amount, 3-5/day
That is what i understand as well.
Fair enough
400 Mg? sounds orders of magnitude beyond lethal. How do you even shove all that into your system?
Thats like 4 standard cups of coffee throughout the day lol. I strictly work 12 hour shifts. So, on my overnights I do about 100 mg on the way in and a few more coffees/energy drinks through the night. If I go to the gym I do another 100 mg right before I start lifting. Day shifts I’ll do 100 on the way in and usually a mid day coffee or a coffee before I hit the gym. I also have ADHD so caffeine hits me kinda weakly.
I think it’s a joke about Mg vs mg.
Lol
Exactly. Capital letters matter in science and technology.
Oh, ok so that was only a 10⁹ times more… No biggie. LOL.
Anyway, as long as you’re able to sleep well, it should be ok. Personally, I think 2 cups (2*200 ml) is a good amount for me. The exact amount of caffeine that contains depends on the type of coffee beans I use. The concentration in the drinkable liquid should be around 300 mg/l, but who knows really. Dark roast will have less than light roast. In any case, that could be something like 2cups/d *0.2 l/cup *300 mg/l = 120 mg/d. Compared to that, I would still say your caffeine intake is a lot higher than mine.
Anyway, as a fun thought experiment, I looked up what caffeine costs and what it would take to buy 400 Mg of it. Sigma-Aldrich/Merck sells 25 kg drums of this stuff and they charge only 1060 € for each. What a bargain for food grade caffeine!
That means, you would need to order 16 000 drums of it. That will be quite a few pallets. Is that going to be more than a single lorry? Don’t worry about it. It will cost you only 16 960 000 €, so I guess now would be a good time to start a company to get those tax deductions on chemical orders. On the other hand, you might actually want to contact one of the many factories that produce decaf beans and ask for a better price. All of that caffeine has to go somewhere, right?
Usually, I would recommend using gloves, respirator, full hazmat suit etc. when handling this kind of cargo, but in this case that would kinda defeat the purpose.

Zero.
There are too few of us.
Also zero, for like 20 years now.
Maybe the occasional sip of coffee if I have a headache

Hahaha
Found the mormans.
I don’t know man, I can’t really think of many drugs I haven’t done in some form or another. I just don’t use stimulants anymore, as I’ve already enough problems being overstimulated.
I drink to make other people more interesting.

Edit Also how do you know we aren’t morwomans instead of mormans?
I like to boof a pot of coffee in the morning.
The silent majority has been real silent in this thread — but thank you for speaking up for proper technique.
I somewhat recently found out my SO thought boofing was just chugging. The revelation and explanation changed the meaning of a decade of jokes in an instant.
It’s not just chugging, it’s butt-chugging
TIL
Hell yeah
Completely random amounts of black coffee and espresso, ranging from an entire pot or 4+ shots of espresso a day to months without bothering.
Between this and your name, you are my kind of people loll
None anymore. It took me a while to realize the the most energetic and level headed people that I know in my life don’t even consume caffeine.
Caffeine addition keeps you permanently tired and getting the next hit just brings you back up closer to to the energy levels of people who don’t consume it.
It is hard as hell to quit because it is so addictive, but the other side is so much better…
I go through periods of high and low caffeine intake, so I have some experience in managing withdrawals.
Let’s say you want to go down from 4 cups to 2 cups. Here’s how to do it:
- Write down how much you currently use. Let’s say you’re using the traditional 60 g/l recipe and a 200 ml cup. Therefore your starting point is: 60 g/l × 0.2 l × 4 cups/d = 48 g/d
- Prepare a daily plan on how do you go from 48 g/d (4 cups/d) to 24 g/d (2 cups/d). I would recommending reducing the does by 1 g of beans per day. So, if you used 48 g of beans yesterday, grind only 47 g today and 46 tomorrow etc. If headaches occur, you need to go slower. If you’re drinking dark roast or if you have a headache resistant head, you can probably get away with 1.5 g/d or 2 g/d reduction rate.
- Don’t switch to another type of coffee while ramping down your intake, since the different caffeine concentration in the beans will change the daily dose. You don’t know the mass of caffeine, but you do know the mass of the beans you grind. Don’t introduce unknown variables. This is hard enough as it is.
- Don’t drink coffee made by other people. You won’t be able to control your intake properly.
That’s how I do it when ramping down my intake. You can also go all the way to zero if you like. The same logic applies to tea as well, but doing it gets a bit tricky. The concentration of caffeine in the solids is much higher in tea, so 1 g/d reduction rate is far too rapid. You also need to have a good scale, and you need to weigh very small masses, which may require some trickery.
This is not true for everyone
de nile is not just a river in egypt
And science is science
And caffeine is drugs
Half-caf, three cups per day (about 150mg total).
That adds up to a caf and a half.
1.5 caf
Interesting move
do you make it?
I can’t find any good roasters that make half caf blends. usually at best they have one mediocre decaf. occasionally there is a really good decaf and i will just blend it myself 50/50 with another coffee.
only one roaster around me makes half caf and it’s not regularly available.
When I brew coffee, I use half regular grounds and half decaf. There are some roasters that make half caf, but it’s easy to mix it yourself.
I’m in Ontario, I’ve been drinking Kicking Horse lately and it’s decent.
Coffee, yerba mate and cola.
No idea how that works out in mg, but I have 2 or so coffees a day, both of which are double shots, and then normally a mate and/or a pepsi or two
Sometimes I drink 3 or 4 coffees in a day, but I tend to go down to single shots after the 2nd one
Hell yeah
However much is in the chocolate bar I eat once or twice a week.
minimum of 1 cup of coffee and 1 cup of tea per day. sometimes more.
i can’t drink caffeine after 3pm or coffee after noon.
No need for me to comment. This guy has me covered.
Except I can drink caffeine in the evening too, IDGAF
I snort it directly off of my The Real Book
The most proper use for a Real Book.
Sick
Don’t bother with the caffeine pills. My brother went through a phase where he was taking these like breath mints, but it was doing more harm then good.
If you feel like you need more caffeine than what coffee or soda provides, then you have a bigger problem that needs attention, and the caffeine is just a bandaid treating the symptoms of the deeper issue.
Yeah the pills would just be a replacement for the energy drinks that everyone says Will kill me.
How familiar are you with ADHD?
They’re about to be very.
There were signs….
I don’t, I have a medical condition that can make people sensitive to caffeine and I am one of those people. I honestly appreciate not relying on a stimulant anymore. I had already severely reduced my intake prior to my condition and I don’t miss it. I sleep better and feel better in general without it.
Same
Yeah if I didn’t work the weird ass swing shift I do I’d probably try to stop.
Not throwing shade, but caffeine is a crutch.
If you ditched it, it would suck for a few months sure, but then your brain will adjust.
I’ve been caffeine free for over 20 years. If I stay up super late, or wake up super early, I struggle for a moment, but then I’m fine.
Water is my go to in the morning.
Your body is so used to caffeine, that you’re literally medicating yourself for a condition you created for yourself. You need it in the morning on a weird shift, because you always use it in the morning on a weird shift.
Again, sorry for the rant, I just feel very strongly about this scientific fact.
Best wishes to you
I completely agree. I used to be a huge coffee drinker until I came to the realization that it’s horrible for my sleep and anxiety, so I weaned myself off it for a few months and then stopped.
Two years without caffeine and I’ll never start using it again. It’s so nice not being addicted to coffee (and not spending money on it), not feeling wired/jittery and not getting withdrawal headaches. I just wake up and I’m ready to go every morning.
Nice! That’s the thing, right? That’s the key I don’t think people understand.
My normal energy level, once I’ve woken up for a few minutes, is how I used to feel when caffeinated, after having been on the stuff for awhile.
The low energy they feel, is literally the caffeine addiction talking. Your body gets so used to it, you’re not feeling the buzz you felt when you first tried it, you’re just maintaining a normal human level of energy, but it feels like a buzz because without it your brain is so addicted that it’s suffering for it.
Crazy.
Now I still have a little caffeine for a really bad headache I can’t shake. But it only takes a few sips of coffee or pop, and I’m good. It’s not enough to make me feel wired, but I still might struggle to fall asleep that night, when normally I don’t struggle at all.
Caffeine IS powerful, people just get used to it, but their body is still affected every day.
Its tough for me because I don’t work a consistent schedule. I work in a 28 day cycle. In total 14 days off, 7 days of 7 am-7pm and 7 days of 7 pm to 7 am, all mixed up.
