I also press F, but for grading the author, not as a sign of respect.

It doesn’t exactly inspire confidence into the reliability of expert assessments, when this is the kind of textbook used to train them.

    I have the same issue. I can take 300 mg and then fall asleep. I had a spinal tap this spring and as I get post-spinal headaches they gave me a lot of caffeine and when I fell asleep they were somewhat weirded out. But I am being tested for ADHD which it might be linked to.

      It is and it’s normal. When I was taking medicine to help with ADHD I could drink a huge coffee and then go to sleep. I stopped taking ADHD medicine 15-20 years ago (mainly due to side effects and being rebellious against my parents) but I still have a weird relationship with caffeine. 3 coffees to even feel it at all, and one just makes me sleepy.

        People with ADHD have something called a paradoxical effect with stimulants. It’s related to the differences in brain chemistry, and it’s why amphetamines are a useful pharmaceutical therapy for those with ADHD while having something more akin to a recreational effect on the neurotypical.

          What fucks me up is that i don’t even get the paradoxical effect, and i’m hesitant to chug 600mg of caffeine to see if that does anything to me

            Sometimes the paradoxical effect is just nothing, or very limited expected effect. The name is a bit of a misnomer in the sense that stimulants don’t have an opposite effect, but rather they are inducing stimulation where it is lacking for ADHD. So instead of getting this rush of energy and focus that a neurotypical individual would, those with ADHD are merely reaching a “normal” level of stimulation by compensating for a lack thereof. In essence the stimulants aren’t acting differently with ADHD, instead their action is compensation. You can see evidence of this in that those properly undergoing amphetamine therapy will still have some side effects of stimulants (e.g. reduced appetite).

            At least this is how I understand it. I’m only a nurse, so I very well could have some misunderstanding here that hasn’t been corrected.

        I call them my coffee naps. 3 cups and then i go pass out for two hours. And I just got diagnosed with ADHD this week. Wasn’t aware of the relationship between the two.

      This is 100% ADHD. I can drink coffee right before going to bed and sleep like a baby. It has to do with the way our brain needs energy. I find that caffeine calms me down because my brain finally has enough energy to regulate my attention.

        It can be and is one of the reasons why I am in the process of diagnosis. The issue is that it is not easy as the traits of ADHD and PTSD have a lot of overlap. There are two things why I do think it is both is this. Another is that I do get pretty intense hyperfocus.
