i have ADHD and caffeine sometimes makes me tired but other times it really gets me going. i can drink coffee at midnight and still go to sleep okay.
asian canned coffee doesnt generally have much caffeine though, most of it is 50%+ milk and sugar

that's why it tastes so nasty though.
shelf stable canned milk always has that fucked up burnt taste to it.

there is a thing with adhd and other mentals where caffeine chills them out but there are also people who are effectively immune. it takes a gallon of coffee before i notice anything. ive quit cold turkey and not noticed anything. but it smells nice and has no calories so i keep coming back

it's tolerance. i remember my first job i was typically drinking 4 cups of coffee + red bull at 5:30pm on the way to the gym and was always soundly in bed by 10pm. nowadays i drink one cup of coffee and i won't be able to sleep until like 5am

for me when i drink green tea at night or late in the afternoon i can't sleep until the morning but a lot of times when i drank it in the morning if i was at home that day i ended up falling asleep shortly after. it's weird

I have ADHD and if I drink caffine after 5pm I will not get any sleep. Although I have chronic insomnia regardless

Those drinks are low in caffeine and they taste gross. I don't understand the obsession with those Japanese vending machines.

>I've seen scenes in multiple manga

So? Where else is reality represented in your gay little china comics?

>>22043117
Every old person I know drinks coffee all fuckin day and sleeps fine. Maybe you're just gay

>>22043117
It might just tolerance up to a point. I don't think they actually sleep well though, they might be in bed but not sleeping.

surprised no one has mentioned it but somewhere around 10% of the global population is caffeine-hyposensitive and just straight up basically don't feel it, and another 50% of the entire global population has the CYP1A2 gene allowing them to metabolize is extremely quickly (~2-3x faster than baseline without the gene)

i am personally hyposensitive and can drink 1-2 grams of caffeine (12-24 cups of drip coffee/2 full pots) and not get noticeable side effects
i stopped doing that for my hearts sake now that i'm on medication, but was always interesting that i just can't relate to people getting the jitters or anxiety and whatnot from caffeine intake, have never felt it

>B vitamin sucking the same one(s) ADD are low on

Longer tea drinking adaptation presumably. Anecdotally, know a few Asians that jade no issue with getting wired off post-dinner coffee.

Weird. I comment here only a few times a week. I guess I live rent free in your tiny, retard, boy-loving brain.

Its the trade off they got in exchange for dying from the common cold

Part Asian, mostly white.
I had a weak tea around 7pm the other day and couldn't get to sleep until 2 in the morning but my grandmother would have, like, eight bowls of tea in a day and sleep like a very winked baby.
Either it depends person to person or my Alpine genes completely undid the Mongol ones.

Japanese guy here. It's usually because we're either studying late / working late so I guess our tolerance is higher. Naturally, our culture of having tea on hand at meals probably doesn't help. Things like barley tea for summer, coffee for whenever, etc. I drink caffeinated drinks even if it makes me sleepy because I just need the extra boost while studying overnight.
