2. I'm toying with a character (in a completely different story) who is, thanks to some kind of brain injury, utterly unable to sleep. Googling for this is difficult because I'm not after insomnia or apnea, but actual physical damage to the sleep center of the brain. I know Lawrence Block created a character (Evan Tanner) that this happened to, but I can't even find enough details to be certain that this is an actual legitimate situation, rather than Block taking creative license. (And then there's the Nancy Kress sf series.) Can anyone point me in some research directions?
ETA: looks like number 2 might be a non-starter. If you're interested, check out
MANY thanks. I love this community.
