Sleep issues run in my family. My uncle sleep walks. My father worked nights for decades by choice. I've experienced weird altered mental states while sleeping, and always had problems sleeping. My kid is experiencing some of the same stuff. Caffeine definitely exacerbated my problem. But quitting caffeine alone was not enough. Avoiding screens (and using f.lux), making my bed a 'sacred space' where only sex and sleep happen (although I still read fiction in it because it helps me nod off), using a red light, and a few other things have also been necessary and even then I sometimes have trouble sleeping. My kid is experiencing much the same problems and she is not allowed to have caffeine. I'm trying to teach her good sleep hygiene, but the things she's describing and the things I see are very very similar to the things I went through as a teen and sometimes still struggle with. It may or may not be a coincidence that we trace a significant portion of our ancestry back to places of high latitude. In fact, now I'm kind of curious to ask some of my distance cousins if they've had any of the same issues.
