hello dear pjd,
I would rather take herbal medicine, than the hard stuff -
but I do realize, there are many side effects from the drugs, and we must be careful when using an anti depression medications and valerian root,
it made me very depressed...it was called formula 303...
Formula 303's Ingredients:

Valerian Root (Valeriana officinalis) - used for centuries to calm upset nerves and for treating mood problems, pain and headache. Today homeopaths and herbalists use Valerian root for its antispasmodic, calmative, tranquilizing, carminative (good for upset stomach and digestion) and pain relieving effects. (approximately 264 mg)

Passion Flower (Passiflora incarnata) - discovered in 1569 it is primarily used as a sedative or nervine to combat excess nervousness and anxiety, to tranquilize, and to promote sleep; as an anodyne, anti-spasmodic and anti-convulsant to treat dysmenorrhea, muscle cramps, and so forth. (approximately 132 mg)

Magnesium - is one of the most important essential minerals to promote proper nerve function. It is a key element in the stabilization of nerve cells, without which, the nerves would be in a constant state of excitation (a state known as tetany.) (approximately 65 mg)
