There is usually a loss of appetite with aversion to all food and drink. A particular aversion is to sour things of all kinds but also to cheese.
Eating and drinking will also aggravate all affections and symptoms. This is especially true for cold things, for coffee, tobacco, alcohol and so on. For example the patient may be very nervous after one glass of wine, or may get nausea and vomiting after the smell of a cigar.
Sometimes there is a hungry feeling in the pit of the stomach which may continue the whole day, but which is hardly relieved by eating. It has been described in the proving as a ‘sensation in stomach as if one had been a long time without food till hunger was gone’. But the aversion and disgust for food, which is so intense that it can be compared with Colchicum, may continue notwithstanding the hungry feeling.
Anorexia nervosa, caused by grief, mental excitement, etc. Bulimia. In a ‘classical’ case of ‘amenorrhoea with insanity’ the patient suffered with fixed ideas concerning eating: didn’t want to eat anything, or nothing but bread and water; then again eating with a ravenous and greedy appetite.
The desires for certain kinds of food and drink are rare but one has been confirmed: thirst for cold drinks, especially beer (which may or may not agree). Desire for mustard and aversion cheese.
Nausea and inclination to vomit are, of course, very frequent symptoms in Cocculus patients. They are often coupled with a whirling vertigo, sometimes with headache. ‘Inclination to vomit, associated with headache, and pain in the intestines as if bruised’. Nausea may even accompany complaints like sciatica.
Well known are certain causes and modalities: nausea caused by riding in a car or boat; by motion, especially of the eyes, by rising in bed, lifting the head etc. ‘In the morning she is scarcely able to rise in bed on account of sickness and inclination to vomit’. ‘Becomes sick by looking at the pitching of a vessel’.
Some more peculiarities of the nausea:
It will come on from smelling food, but also when looking at it, when thinking of it, even when someone else talks about eating. As Kent says, ‘You go to the bedside and you ask the nurse, “What have you been feeding the patient?” and the patient gags’.
