Non-benzodiazepine sedative hypnotics are Zolpidem (Ambien, Ambien CR, generic), Zaleplon (Sonata),
Eszopiclone (Lunesta), and Ramelteon (Rozerem) which is the newest type of sedative hypnotic but it is not technically a non-benzodiazepine hypnotic.
Be sure to read the section in the middle since it contrasts the different meds.

Chamomile tea, warm milk and things like that never worked for me.
