Anecdote of one: I stopped taking L-Theanine because I would experience a noticeable comedown of apathy two days later.
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.
What makes you think that?
