From the discussions I've seen about theanine, the real benefit supposedly came when it was taken alongside caffeine. The thinking being that theanine moderated some of the jittery effects of caffeine, allowing the user to take higher doses of caffeine, which itself has some benefit on task concentration and focus.

I wish the author had spent time addressing that theory specifically.

I don't understand what people refer to when they say "jittery effects". I don't feel anything when taking caffeine, no matter the dose. Or I want to think it helps me wake up but the effect is so small that I can't be sure. It's basically just a ritual for me.

Do you have ADHD?

Most neurotypical people seem to experience jittery effects and being extremely alert while for people with ADHD it can actually make them sleepy.

Of course everyone's brain is different, it is just a correlation with many exceptions. So yeah, caffeine works differently on different people.

Personally, as someone with ADHD, I have a crazy caffeine tolerance. It helps me somewhat with focus but I don't get jittery.

I do.

I think there's another dimension of temporal tolerance to consider.

There have been times in my life where I consumed a lot of caffeine, and it brought on the paradoxical sleepy effect.

And other times where I tried to eliminate caffeine, and a fallen-off-the-wagon strong dose gets me jittery, but acclimation happens in 24-48 hours.
