As for Melatonin Adverse Events, it's my site that's linked to under 'Uses', (http://www.drugcite.com/?q=melatonin) It's important to sort the data by age and gender as the AE's can vary greatly. That data is FDA FAERS data that runs against many other datasets by the way.
As I've pointed out in the past to you, I'm not sure what use we're supposed to be making of your admittedly nice site, given that we don't know how many people are using melatonin, how reliable any of these cases are, or what.
