probably discover at least some of the following characteristics: fastidiousness, miserliness, a certain degree of insecurity, discontentment, restlessness coupled with weakness, censoriousness, and irritability. The irritability is seen primarily in the morning upon waking, morning being a difficult time for Arsenicum. In more advanced stages the anxiety is also frequently aggravated in the morning. At this stage, particularly if the complaints are more functional and not involving much physical pathology, it may be difficult to separate Arsenicum from Nux vomica. One must then search carefully for the psychological tendencies. Arsenicum will tend to be more insecure, needing the support of other people, whereas Nux uomica will be more self-reliant and impulsive.
In the second stage, as the illness penetrates deeper, the anxiety of Arsenicum becomes more pronounced and an anxious restlessness ensues. The anxiety tends to be most pronounced after midnight and in the morning on waking. The Arsenicum person may awaken in a panic during the hours of 12 to 2 AM. He may say that he is anxious even while asleep. Arsenicum will also at this stage display a prominent fear of being alone. There will be a constant need for company, particularly at night. The fears of Arsenicum are tremendously heightened while alone. His senses become more acute, especially his hearing (though less than that encountered in Coffea and Nux uomica). A fear of robbers is most characteristic of Arsenicum (also Natrum muriaticum).
The anxiety of Arsenicum causes great internal anguish, and it is out of this anguish that the familiar restlessness of Arsenicum arises. The restlessness is not just a physical process; it is primarily a mental restlessness, an attempt to allay the deep-seated anxiety. The restlessness compels the Arsenicum individual to pace to and fro, to move from chair to chair, from bed to bed, but the motion and the changes in position do not ameliorate his symptoms nor his anxiety; on the contrary, his moving about totally exhausts him. The greater the suffering, the more the anguish; the more the restlessness, the more the exhaustion. Similarly the anxiety, which can easily reach the level of anguish will drive the patient from person to person, constantly seeking reassurance and support. Earlier in the course of the pathological development of Arsenicum the restlessness can appear periodically, rising and falling over periods of weeks.
The restlessness of Arsenicum invites comparison with other restless remedies. In Arsenicum the restlessness occurs in conjunction with
