L-theanine is the active non-sedative anxiolytic in green tea that gives it such a "smooth high" when combined with its methylxanthine stimulants, theobromine and caffeine - which are natural pesticides, by the way.

Anecdote of one: I stopped taking L-Theanine because I would experience a noticeable comedown of apathy two days later.

Saying that theobromine and caffeine are pesticidal isn't particularly informative. Most secondary plant metabolites are likely to be pesticides, since there's a tremendous benefit to discouraging small animals from eating your lignified cells. Ascorbic acid is also a pesticide and fungicide, can dissolve bones down to calcium carbonate, yet it is critical to human life.

This was also my experience, but not two days later - the same day. I'd take L-Theanine, feel okay for a few hours, then feel extremely irritable and anxious for the rest of the day. More L-Theanine didn't help.

Is there any statistics on whether women drink more green tea than men? It certainly seems that way.

What makes you think that?

Exactly this happens to me as well.
I believe it's present in all teas: black, oolong, white etc... as well as green.
That would make sense as all of those are the same plant, just harvested at different times and treated differently.
Just a quick note of appreciation regarding the come down observation - I’ve been weaning down my caffeine to minimal but do want to keep the option open and not get too amped if I decide to have a caffeine day.
