I have. I can drink green tea (including strong matcha), which does contain l-theanine, probably daily, but I cannot drink coffee daily for more than maybe 2 weeks without experiencing adverse affects. Even one cup of coffee can leave me agitated. Supplementing coffee with l-theanine completely eliminates agitation.

Can you drink cola without adverse effects? Because I can. And coffee gives me issues after a week or two. Therefore something seems wrong about giving caffeine all the blame.

    Yes, I think so. I drank a lot of (diet) cola at some point, like 1 gallon a day. Never got any issues similar to the ones I got from coffee.

      A gallon of diet coke has less caffeine than one Starbucks venti drip coffee (~380mg vs ~400mg). How much coffee do/did you drink per day?
      - amelius 5y ago
        Like 3-5 regular cups a day (not Starbucks). Then after two weeks even 1 cup became too much. Switching to a gallon of cola then didn't cause any problems.

  I don't drink soft drinks generally, and certainly not in those quantities, but I vaguely recall feeling anxious after drinking cola before. > Therefore something seems wrong about giving caffeine all the blame. Possibly, but in this case, my primary comparison is between coffee and coffee with l-theanine and that one difference by itself produces a very noticeable difference in effect. I do not know what else in coffee could be producing jitters other than the caffeine. Or what in the cola could perhaps be inhibiting the effects of caffeine.

Black tea is also very high in l-theanine. Regular green tea is not, but matcha (which you consume) is as well.

  I can also drink black tea for longer durations than unsupplemented coffee. When I drink green tea, my typical choice is sencha, but it is not nearly as concentrated as the matcha. So I suspect the caffeine is therefore lower than my typical cup of coffee, hence the reduced agitation?
