Dark room, deep breathing, meditation, cool room, fan, lavender oil, trazadone, keeping a schedule, having a solid nightly routine....

My Mom falls asleep to the movie 'Harry Potter and the Sorcerer's Stone'. She puts it in the DVD player and she is deep asleep by the time they make it to the lighthouse in the beginning. To be fair, she loves the books and it was an accident that she "trained" herself to fall asleep to the movie.
