Sleep Expert for Tips to Fall Asleep Fast Story

I’m working on a story on How to Go to Sleep Fast: Tips to Help You Fall Asleep Quickly - and I’m looking for a sleep expert or two to weigh in, as far as: some reasons why you can’t fall asleep, special considerations, tips for falling asleep faster, long-term sleep strategies, and more. Please don’t send commentary without emailing me first, as I have specific questions (and I’ll need experts unaffiliated with other mattress brands for this one, please).
