As someone who's told they have pretty intense ADHD, I consider myself lucky to have weird form of narcolepsy. It only really kicks in when I get too comfortable, like lying in bed (don't worry, I don't drive or operate machinery).
This means that when my head hits the pillow at night, I"m out pretty quickly. I can wake up a lot throughout the night, but that's okay.
I see so many folk with ADHD struggle with sleep, their minds racing all night and I don't know how I'd cope with that!
