Cognitive behavioral therapy for insomnia
The first step in treating insomnia with CBT-I is to identify the underlying causes of the insomnia. People with insomnia should evaluate or have their sleep patterns evaluated and take into account all possible factors that may be affecting the person's ability to sleep. This would involve keeping a sleep diary or journal for a couple weeks. The journal will help to identify patterns of thoughts or behaviors, stressors, etc. that could be contributing to the person's insomnia.
Trimipramine
Trimipramine's primary use in medicine is in the treatment of major depressive disorder, especially where sedation is helpful due to its prominent sedative effects. The drug is also an effective anxiolytic, and can be used in the treatment of anxiety. In addition to depression and anxiety, trimipramine is effective in the treatment of insomnia, and unlike most other hypnotics, does not alter the normal sleep architecture. In particular, it does not suppress REM sleep, and dreams are said to "brighten" during treatment. Trimipramine also has some weak antipsychotic effects with a profile of activity described as similar to that of clozapine, and may be useful in the treatment of psychotic symptoms such as in delusional depression or schizophrenia.
