I once was sitting at my desk and had this overwhelming calm come over me. I was trying to figure out what I had eaten that morning/afternoon and then realized the 2-3 'Just Chill' sodas in my trash my mom had gotten me contained L-Theanine. Was a pretty blind test but I wasn't able to reproduce it effectively with L-Theanine supplements I found on amazon.

Very interesting: maybe it could have been something else in the sodas? Alternatively, the quality of the amazon supplement might not have been great (unless you tried from multiple sources)

Quality of L-theanine seems to vary wildly across brands. I’ve had one that does nothing, one that gives me consistent headaches, and one that gives me consistent diarrhea.
