I'm not sure about licensed... doesn't change that they give that shit out like candy. They give this sort of shit out for everything, even nausea and chlorpromazine. They (those in power) do not want you to think deeply. And yes, orexin antagonists are supposed to have an abuse potential akin to melatonin. I have a feeling there gonna just be the next benedryl for sleep. Not super useful but super accessible and better than nothing. They've also got a low ass ceiling dose iirc. I'm not hopeful they'll be great for insomnia.
