I have used Melatonin for about 6 years for my son. I suffered so long with no sleep I didn't want to give anything but the sleep issues were dificult the best decision I ever made. I use Natures Harmony I get it at Superstore.

There is a spray melatonin called Siesta from a company called Biocare Health www.biocarehealth.net.  Works quickly and the sray format is so convenient.  You can get it at Zellers paharmacies and Rexall & Pharmaplus stores, you can also order direct from thre company
