I've recently become a NMH listener as well, and I'm a fan. I don't need it every night, but definitely it's part of the overall package for getting good sleep under stress, along with screen hygiene, physical activity, and light cannabis use.
There's a website and merch too, though I just listen for free on Castbox, which has a nice option to shut itself down at the end of the episode: https://www.nothingmuchhappens.com/kathryn
