Heath, I will assume you are seeing a therapest and you don't want another perscription or thay are to expensive for me melatonin helped me but only for a few months you can take about 10mg a day ( a night ) for a few months start with 3 it will corect a minor imbalence for a wile but it's a tollernce thing also once your body has enof of it it will dump the rest kinda like vit c. OTC's are ushaly not very good and shuld only be used once or twice a week AT MOST. if you are haveing consitant problems you may have to get a persciption ask your doctor for samples.
cammimeal tea is also help full to me I also have a major depresive disorder and alot of truble sleeping,
may i ask what other medications you are taking ? some thing are contraindicated for some of the lissed ones inculding melitonin, I would not want you to get sick.
