I'm wondering what medication helps insomnia?

Cause?: Depends on the cause of the insomnia. Medications can be helpful but not curative if the insomnia, per se, is caused by anxiety, panic or another primary sleep disorder. Also some medications used to treat insomnia can worsen other medical conditions. See someone that treats these things all the time.

There are many : Options such as antihistamines, melatonin, chamomile, valarian root, trazodone, ambien, halcion, lunestia, rozerem, silenor, sonata (zaleplon) etc.
