Research by professor Charles Morin has demonstrated that psychotherapy, and specifically cognitive-behavioral therapy (CBT), is more efficient than drugs to treat insomnia.  According to data presented last Thursday by Dr. Morin at the annual meeting of the Quebec psychiatric association, drugs work, but have effects that vary from weak to moderate, depending on the insomnia component being measured (number of awakenings per night, length of sleep, etc...), while the effect of cognitive-behavioral therapy varies from moderate to strong.
