I've been struggling with coffee-induced anxiety and afternoon crashes. Tried matcha (too much prep) and mushroom coffee (digestive issues). Recently discovered puer tea has a better L-theanine:caffeine ratio for calm focus.

I'm exploring whether there's demand for a convenient puer concentrate and put together a quick survey (2-3 min): https://aicofounder.com/research/ElEORiN

Curious what's working for the HN crowd—especially folks doing deep work who've moved away from traditional coffee?
