Question: Thanks for your time!
  
  I've seen suggestions of a link between sleep disruption (insomnia, circadian misalignment, etc) and ADHD in some people, but nothing beyond "these things seem like they might be correlated, try to sleep better if you can!" In your research, have you come across anything suggesting such a link, and can you tell us more about it?
Answer: There is a lot of research on this topic.  We know with certainty that ADHD people are more likely than others to have a sleep disorder even those that have never used medications for ADHD.
