        Let's face it you're mentally challenged and it shows.
        The spider test doesn't specify any specific caffeine dose and is irrelevant for humans due to differences in metabolization.

        As for the CBF, it entirely ignores that caffeine as an adenosin antagonist leads to an increase of adenosin receptors.
        And more receptors lead to an increase in blood flow.
        tl;dr you're a tard.

      Just drink green tea. It's not quitting caffeine but significantly reducing intake. The L Theanine in green tea will counteract the jittery effect of the low caffeine content (30 mg vs 90 mg in coffee). You'll feel much clearer.

      Maybe it takes more than 2 or 3 weeks for you to reach baseline. Taper slowly if you can't just bite the bullet, and do it disciplined and planned out like exercise so you can't fuck it up. I.e. 2 cups of coffee or less each day for a week or 2, 1 cup or less each day for a week or 2, half cup coffee or 1 cup green tea each day for a week or 2. That can be a 6 week taper if you really need it to be. Don't bullshit yourself about a 24 oz from Starbucks being one cup of coffee also. Standard 8-12 oz serving. Carry around a travel mug and have them put coffee in it like an absolute autist if you really need to. Being an absolute autist about tapering my consumer is how I'm still 5 years free from smoking.

      Maybe your dopamine etc. was just drained. But yeah, caffeine builds up a tolerance really fast. Something like 100mg for one week or 400mg or 3 days and you will have some slight withdrawl symptoms.

      Extremely quickly. I tend to use caffeine until the 400mg a day limit doesn't do anything for me. Then I cleanse for 2-8 weeks and start using caffeine again. I am usually back to baseline (feeling something with usage, but not super energetic anymore) within 2 days of resuming caffeine usage, especially if I'm utilizing energy drinks and not just diet sodas or teas.

      I've read that caffeine has a half-life of about 8 hours, so you can probably think of it as drinking half an espresso at 10pm. I'd recommend not drinking more after 4pm or 2pm even. Caffeine majorly fucks with your sleep, I experienced it firsthand for years as a kid and had no idea about it. Unfortunately found out way too fucking late. Note that there's loads of caffeine in regular drinks like tea or coke.
      Also caffeine is addictive, as in, you'll have withdrawals if you stop using it. If you're a fairly heavy user as you describe I would recommend drinking less over time rather than quitting cold turkey, it can actually fuck you up.

      Not necessarily but it can.
      Half time and turn total elimination time if caffeine can vary wildly between people and increase depending on liver function, medication, dosage etc.
      If you're really unlucky it could take you over 12 hours until no caffeine is in your system.
      Although of course low concentrations have negligible effects.

    study doesn't say much beyond that all caffeine users appear to have reduced CBF compared to non-users, as to how this translates to real outcomes (taking into account their confounding factors for failure to control for prior or recent use), there's nothing to conclude or discuss at a result of the data.
    studies are only as good as the endpoints collected, and in this case, it doesn't tell you much because people aren't dropping dead from drinking coffee and many of the productive class are caffeine addicts, which doesn't follow the logic of this reduction in CBF resulting in impairment.
    unfortunately the discussion section doesn't touch any of the theoretical basis for why the fuck this matters besides CBF lower = bad, probably because they have no valuable theoretical basis to put forward, which heavily devalues the study overall.

    >Evidence from receptor binding, physiology, and behavioral studies suggest an adaptation to the effects of caffeine following chronic intake. This adaptation presumably accounts for the development of tolerance to the vasoconstrictive and neurostimulant effects of caffeine. Some evidence exists for the sensitization (e.g. conversion to high affinity state) of adenosine receptors following chronic caffeine use [Green and Stiles,1986], whereas receptor binding studies suggest that the majority of this adaptation is due to receptor upregulation (e.g. increase in receptor number)

    Why are you not cycling caffeine to boost your adenosine receptors?
