I use caffeine very sparingly, rather than daily or weekly. For pain relief as an "analgesic stack" Caffeine (60mg - 120mg) synergizes with Acetaminophen (1000mg) and Ibuprofen (400mg - 1200mg) for AMAZING pain relief. For tests and exams, especially early morning, when I need a bit of an extra stimulant to focus and not go ADHD. For competitions or tests for certifications when I need a physical performance boost. Otherwise, I completely avoid the stuff as much as I can.

Drinking your 1st cup of coffee after going caffeine free for almost a year was the most euphoric experience. I used to drink upwards of 500 mg a day for years and years, and I had built up a tolerance. Stopping at the gas station a few times a day to get an energy drink and it almost making me sleepy instead of giving me energy, I knew I needed to Completely take a break from caffeine. I’m about two years in drinking coffee again and caffeine, now 1 cappuccino in the morning, really puts me in an incredible mood.

[@liamwaters5451]

Caffeine does not make me happy anymore. Found once i hit 28 it started giving me servere anxiety all the time, i couldnt sleep at all and i was freaking out over the most insignificant of things. So i had to stop. once i got past the horrible withdrawals my brain was relatively back to normal.

I had heart palpitations and agitations a couple of years ago and mind you I only drink one cup per day. I switched to decaf and the heart palpitations and agitation gone. I still drink one cup of decaf a day. I love the taste and the aroma of coffee. I never drank it for the buzz. If you get good quality decaf beans you won't notice the difference in the taste. But if you're solely drinking it for the buzz might be a different matter.

[@firehog]

I was depressed to 11. Caffeine made me handle the day. Turns out that therapy worked better than 2000mg of caffeine a day. Yes, I was THAT tollerant. My doctor joke that my bloodtype was 100% arabica. I should cut down since the nurces wanted to take a shot since my blood was stronger than the coffee at work. He joked yes, but it drove the point to it's mark. After a looooooong time of therapy, I drink a cup, perhaps 2 every day. No bad health effects either. My doctor ran a bunch of test on me to see but found nothing. Sadly, he retired after that. Dang it. Loved the guy. My new one is cool. Reminds me of you, but european

When I was 8 in 1976, my family doctor told my parents to give me coffee to counteract my hyperactivity. I used to drink six pots of coffee for years until about six years ago, when I slowly lowered my coffee intake to two or three cups a day now. Coffee never woke me up; it made me sleepy, and it still does. so is something wired differently in my brain? I always wondered why it had that effect on me.

[@olgaiushkova2454]

Caffeine helped to stimulate your prefrontal lobes cortex, presumably. It's adhders' problem. The same type of brain - I can drink coffee and go to bed. Yet a cup of strong espresso orders my thoughts, disciplines them and slows down their wandering around

[@kuyab9122]

some people experience a paradoxical calming or sedating effect especially if they’re naturally high energy or have certain types of neurodivergence like ADHD.

2 questions: - why do we get rid off adenosine while sleeping? Doesn't our brain spend ATP as well?

For most people 1 or 3 cups of coffee is fine however as for sugar 20 to 40 teaspoon of sugar per day is probably not OK for most people and this is what the average american consumes on the daily of both of these.

Tea has L-theanine in addition to caffeine. The effects of both together is what makes drinking tea a more pleasant experience. L-theanine produces a calming/relaxing and more focused state.

LOL...plenty of ifs ands and buts in here. However, I am a tea drinker: strong, black tea with no additives. Hot or iced, depending on season. In summer, I go through a 2 quart pitcher of iced tea in as many days. In winter, I have hot tea in the morning, and sometimes iced tea or soda with dinner...although I"ve cut way back on the soda for several reasons. A friend of ours, however, is a staunch coffee-holic, and claims to drink "only one cup of coffee a day." That said, his coffee mug is gigantic, and holds TWO ENTIRE POTS of coffee!!! He's been doing this for so many years that he's virtually immune to the effects, but would probably suffer badly from withdrawals. I can drink tea a night and still sleep okay; it's other issues that give me insomnia (ongoing grief; stress, anxiety, etc.). Tea doesn't stress me. I have my morning tea, and/or iced tea later in the day, and can still fall asleep on the couch in the middle of the day. (Oh, yeah--I'm 76 years old, so maybe naps are a thing now, anyway. LOL)

I have ADHD. I have one 200mg caffeinated energy drink 1st thing in the morning and it helps me focus. If I don't have it, my head is like a 3 ring circus. It's all I have all day and it works wonders for me.

So you rely on caffeine and have an addiction. Not good

I had Supra Ventricular Tachycardia . Eventually having an RF Ablation. I am no stranger to ADENOSINE pushes intraveinously to "snap my heart rate back form 180 beats /minute to normal. Can you explain why ADENOSINE pushes are so dramatic to the patient and why only ambulance paramedics are allowed to carry it or the Emergency ward ? Plus why do they administer Adenosine ? Cheers.

It would be very interesting at the cellular level to look at the caffeine effect on GABA receptors(an inhibitory neurotransmitter).

13:39 Sugar & Caffeine makes me pee like a thunderstorm 😂. It's also known to flush out key minerals such as Iron & Magnesium, especially in women.

Unfortunately, caffeine is only effective in increasing productivity the first day or two that you take it. After that, you level back out to normal levels and HAVE to take caffeine in order to remain at normal levels (unless you detox from it). So, if you are going to drink it or ingest it, better to do so once a week, to truly gain the benefits.

I don't know if anyone addressed this in the comments, but is there any known relationship between coffee drinking and narcolepsy? After at least a dozen sleep studies, I was diagnosed with narcolepsy in 2021 -- at age 64 (?) ! How did I get to be 64 before I was diagnosed? If there's a relationship between coffee consumption and narcolepsy, I'm guessing it's tenuous at best: I started drinking coffee when I was in my teens. I've never noticed any effect from coffee -- except that it tastes good and feels good going down my throat.

Amazing informative video👏🏻👏🏻

Is all caffeine created equal?

[@saturn3955]

i don’t think so. ever tried yerba mate? it doesn’t feel like coffee at all no matter how much you drink you get energy but it’s so much more mellow, for me it more just feels like it makes you happy rather than super energized like coffee

[@TheYerjustaface]

I drink lots of caffeine. I have to take etomidate to get rid of the jitters
