I take a tincture of a strong Kava extract plus a good dose of Source Naturals' sublingual time released melatonin. That combo works great. The Kava chills your nerves and the melatonin gets you into a good sleep cycle. Regular melatonin can wear off in the middle of the night, but the time release lasts all night..plus I hold the sublingual under tongue for at least 5 minutes. Works better like that. However, if you start worrying that you won't fall asleep, you'll get anxious and your brain won't shut off.
