I like to try to get to the original source when attempting to get the benefits from something I ingest. There are sleep teas I bought at the grain store next to Gossips which has camomille, passion flower and other plant material that should relax you. Of course after you find it, brew it and strain it, you should be tired anyway (lol). If you take calcium, take it in the evening along with magnesium, maybe 500 mg. BTW, Ambien is made by Monsanto I read, beware!
