A whole bunch of friends from the town I used to live in. One started peeing on his skin as an eczema treatment, which seemed to work, and somehow this progressed to drinking it. It spread, and became a thing in town. Last I heard there were about 10 pee drinkers, but obviously it’s not something people talk about openly.

Apparently morning pee is relaxing because of the melatonin content?

Edit: Apparently it’s a very old and widespread practice. Here’s a Healthline article on it: https://www.healthline.com/health/drinking-urine
