It's always amusing to read the self-narratives of a bunch of unacknowledged drug addicts when links like this get posted.

unfortunately, it's never amusing to read the thinly-veiled self-narratives of the condescending when comments like this get posted.

After habitually consuming caffeine (not in coffee form) daily, usually multiple times a day, for more than a decade, a horrible mental health incident happened to me that forced me to stop it for a while. Afterwards I didn't resume the habit, and so I no longer have a tolerance. This has let me evaluate what caffeine does with fresh eyes, so to say, because I can now consume it occasionally while having many non-caf…

I had a similiar case with influeza the past december. I didn't eat for 4 days, fever for a long time, and low energy during the whole 4 weeks it took me to get back to normal. I couldn't drink coffee or alcohol during those 4 weeks, and notice that I didn't get any migraines after those 4 weeks even when I, for the past 12 years, knew exactly how I got them reliably. I didn't make sense to me to keep drinking coffee…

I had wild food poisoning and had a similar experience (took me out for weeks, didn’t drink coffee). I assume the body must have some sort of gating mechanism for pain; I have absolutely had caffeine withdrawal before, but not that time. I’ve since cut back and switched to tea, which I believe has helped with my anxiety.

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 –…

The psychoactive effects of caffeine are massive after you detox for a few weeks. I had a full cup after not having caffeine for a month and the effect was massive. Near euphoria, constant task switching, some anxiety, etc. I personally felt the effect was much stronger than weed has ever felt for me and comparable to having 5+ drinks of alcohol.

But the effect quickly drops to almost nothing very rapidly. I started having caffeine 3 out of 7 days because having a low caffeine tolerance was too annoying. One coke, tea, chocolate would completely destroy my sleep.

thirty-one participants were moderate coffee-drinkers (CD, i.e., people that usually consume between 3 to 5 cups of coffee per day). 3-5 is moderate? To me, 3 is already high. Also, sample size is pretty low and they're all Irish.

I drink a small cup in the morning (like 250 ml) and 1-2 Moka pot espressos (like one shot). This typically happens between 7-10am. No more coffee after that most of the time. I like to keep it in the morning routine with breakfast. Green tea and water in my afternoons. Personally, I don't feel any kind of "drug like" effects from this routine. I wonder about the strength of coffee people are drinking and the effects…

It's less about the strength of coffee than about your metabolism. I used to be unaffected by caffeine, and now it takes a few sips in the morning to mess with my sleep in the evening - sth that started happening in my twenties I believe, possibly liver-related.

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 quit caffeine for a year but it didn't work out for me. I felt mentally sluggish all the time; there would be times I'd be staring at my screen with my mind resisting the act of processing any information. I also noticed I became very sensitive with how much sleep I got, and if it was anything less than 8 hours the day would be miserable. I could be a special case here with altered brain development since even as a small child I was drinking liters of black sun tea. So since my withdrawal experiment I've highly regulated my caffeine intake with pills with a maximum of 200mg a day before noon, although I will sometimes cut back to 50-100mg a day during periods when my life isn't running full steam. This has worked out well for me.

I drank a lot of coffee until I forgot to pack instant on a 3 day backpacking trip. Headache the whole time that I cured in 5 minutes by drinking a mt dew the minute we got back to civilization. Figured it wasn't worth it and weaned off.

Then it turned out my rate of getting migraines dropped off considerably. But I love coffee, so I tried decaf. Migraines returned to being more frequent. So that was that.

If I could get it without the side effects, I surely would. Right now I'm drinking a hot cup of delicious roasted barley tea. But it's not the same.

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

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

It was a slight attempt to highlight that the conversation about a purely subjective thing is missing the point entirely. In the context of scientific discovery trying to qualify the outcome based on an individual's personal interpretation of descriptive words is a fool's errand. Attempting to justify one's personal habits or predilections is squarely in the flat earther camp of scientific belief.

I had heart/chest pains from Lisdextroamphetamine (ADHD meds) that went away when I stopped drinking coffee. And I drunk very little, just one half cup in the morning. Much less anxious now too, but that's more likely due to ADHD meds.

Even on the "milder" Methylphenidate you can experince clenching jaw, grinding teeth and a chafed tongue when consuming coffee, tea and even dark chocolate.

all tea has caffeine unless it's decaf. some things that aren't tea are called tea casually, but they aren't tea, for instance peppermint "tea" is not tea. by the same logic that one would call peppermint a tea, one would have to call coffee a tea. and beef broth.

no true scotsman tea. Tea is what is called tea. You can not just decide that you don't like some teas so they are not tea anymore.

did you check wikipedia and found it agrees with me before you came up with that?

Can you actually get caffeine free coffee? I thought most decaf brands where only about 50% less.

You're right that the caffeine isn't entirely removed, but it's supposedly more than 90% removed. (I'm even seeing the number 97% mentioned a lot online.)

The bean is already only like 2% caffeine lol so cheap decaf can definitely really be "half caf" even if they say that.
