Has L-theanine actually done anything for you?

I’ve been experimenting with L-theanine for a while. Sometimes it feels like it genuinely clears mental noise when I start spiraling, but I wonder if it’s placebo.

If you've used it, what did it actually change for you? Did it help with anxiety, brain fog, social ease, stress?

Did it do nothing?

Also curious what dosage range you’ve found noticeable, and whether you take it solo or paired with anything else.
