Seasickness or motion sickness will certainly be affected by the terrain (or chemistry) of the particular person’s system.  Eating lightly will help a lot.  If you are on a cruise and living it up, with alcohol, rich foods, and desserts, of course your susceptibility will increase dramatically. If you fast or eat lightly, drinking clear liquids and water, you will probably recover faster and reoccurrences will be fewer.

If you fairly sure you will be sick, then prophylaxis is indicated.  YOU COULD TAKE Tabacum 30C before the voyage. One homeopathic doctor gives Cocculus 30C  2 days before the voyage. (Or,  iF Petroleum or another remedy has been the cure previously for that person, use this instead) 

The choice of remedy to use depends upon the different symptoms which are exhibited.

If you have time to evaluate the details of the case, they are included  below.  If you want you can try to give remedies in the order of most common first, second, etc.

If you see a very big improvement, and the symptoms return, don’t be shy to repeat the dosing (even often) as needed. (even though they are 1M)  

First Choice:

Petroleum: seasickness with occipital (back of head) headache is petroleum every time. (This may distinguish it from Tabacum) Also,  the sensation of nausea is better with eating, and associated with a sinking feeling in the abdomen and a feeling of general coldness and or coldness in the abdomen.  Also Petroleum patients can be  prone to giddiness when riding in cars, trains and sailing.

Second Choice

Tabacum:  Deathly incessant nausea, pallor (pale), vertigo with cold sweat, coldness,  worse by least motion and better on deck in fresh cold air.  Sometimes coming in paroxysms (spells) and sometimes covered in cold sweat. Nausea is worse with the smell of tobacco smoke, Terrible faint sinking feeling in the pit of the stomach.

Third Choice

Cocculus:   Vertigo is worse by looking at things in motion, agg the condition. Nausea and Vertigo.  Dizziness, also all is made much worse by motion. Very sensitive to motion.  Motion of an object moving past, agg the tremendous vertigo.

Last Choice

Nux Vomica: A deathly paleness and ineffectual attempts to vomit. Retching as if to vomit while hawking mucous from fauces (throat).


Most of the affected passengers appear to be have contracted a Norwalk-like virus, a contagious food-borne virus that causes vomiting, diarrhea and abdominal cramps.

•  From a chat room:

Call it the Cruise Ship Cover up. The dirty secret behind the outbreak of stomach illness on 21 cruises this year is that the cause is other cruise ships in the narrow Caribbean shipping lanes. The big ships routinely dump raw sewage into the ocean. Ships following behind then draw in the polluted sea water for their desalinization plants, which take out the salt, but not all the bacteria. Passengers are soon suffering from diarrhea and vomiting - even if they are careful and drink only bottled water - because they are showering in sewage and brushing their teeth with it. “But no one wants the public to know because it’s just too disgusting,” one nautical expert told us. 

Viral Gastroenteritis

What is viral gastroenteritis?

Gastroenteritis means inflammation of the stomach and small and large intestines. Viral gastroenteritis is an infection caused by a variety of viruses that results in vomiting or diarrhea. It is often called the “stomach flu,” although it is not caused by the influenza viruses.

What causes viral gastroenteritis?

Many different viruses can cause gastroenteritis, including rotaviruses, adenoviruses, caliciviruses, astroviruses, Norwalk virus, and a group of Norwalk-like viruses. Viral gastroenteritis is not caused by bacteria (such as Salmonella or Escherichia coli) or parasites (such as Giardia), or by medications or other medical conditions, although the symptoms may be similar. Your doctor can determine if the diarrhea is caused by a virus or by something else.

What are the symptoms of viral gastroenteritis?

The main symptoms of viral gastroenteritis are watery diarrhea and vomiting. The affected person may also have headache, fever, and abdominal cramps (“stomach ache”). In general, the symptoms begin 1 to 2 days following infection with a virus that causes gastroenteritis and may last for 1 to 10 days, depending on which virus causes the illness.

Is viral gastroenteritis a serious illness?

For most people, it is not. People who get viral gastroenteritis almost always recover completely without any long-term problems. Gastroenteritis is a serious illness, however, for persons who are unable to drink enough fluids to replace what they lose through vomiting or diarrhea. Infants, young children, and persons who are unable to care for themselves, such as the disabled or elderly, are at risk for dehydration from loss of fluids. Immune compromised persons are at risk for dehydration because they may get a more serious illness, with greater vomiting or diarrhea. They may need to be hospitalized for treatment to correct or prevent dehydration.

Is the illness contagious? How are these viruses spread?

Yes, viral gastroenteritis is contagious. The viruses that cause gastroenteritis are spread through close contact with infected persons (for example, by sharing food, water, or eating utensils). Individuals may also become infected by eating or drinking contaminated foods or beverages.

How does food get contaminated by gastroenteritis viruses?

Food may be contaminated by food preparers or handlers who have viral gastroenteritis, especially if they do not wash their hands regularly after using the bathroom. Shellfish may be contaminated by sewage, and persons who eat raw or undercooked shellfish harvested from contaminated waters may get diarrhea. Drinking water can also be contaminated by sewage and be a source of spread of these viruses.

Where and when does viral gastroenteritis occur?

Viral gastroenteritis affects people in all parts of the world. Each virus has its own seasonal activity. For example, in the United States, rotavirus and astrovirus infections occur during the cooler months of the year (October to April), whereas adenovirus infections occur throughout the year. Viral gastroenteritis outbreaks can occur in institutional settings, such as schools, child care facilities, and nursing homes, and can occur in other group settings, such as banquet halls, cruise ships, dormitories, and campgrounds.

Who gets viral gastroenteritis?

Anyone can get it. Viral gastroenteritis occurs in people of all ages and backgrounds. However, some viruses tend to cause diarrheal disease primarily among people in specific age groups. Rotavirus infection is the most common cause of diarrhea in infants and young children under 5 years old. Adenoviruses and astroviruses cause diarrhea mostly in young children, but older children and adults can also be affected. Norwalk and Norwalk-like viruses are more likely to cause diarrhea in older children and adults.

How is viral gastroenteritis diagnosed?

Generally, viral gastroenteritis is diagnosed by a physician on the basis of the symptoms and medical examination of the patient. Rotavirus infection can be diagnosed by laboratory testing of a stool specimen. Tests to detect other viruses that cause gastroenteritis are not in routine use.

How is viral gastroenteritis treated?

The most important of treating viral gastroenteritis in children and adults is to prevent severe loss of fluids (dehydration). This treatment should begin at home. Your physician may give you specific instructions about what kinds of fluid to give. CDC recommends that families with infants and young children keep a supply of oral rehydration solution (ORS) at home at all times and use the solution when diarrhea first occurs in the child. ORS is available at pharmacies without a prescription. Follow the written directions on the ORS package, and use clean or boiled water. Medications, including antibiotics (which have no effect on viruses) and other treatments, should be avoided unless specifically recommended by a physician.

Can viral gastroenteritis be prevented?

Yes. Persons can reduce their chance of getting infected by frequent handwashing, prompt disinfection of contaminated surfaces with household chlorine bleach-based cleaners, and prompt washing of soiled articles of clothing. If food or water is thought to be contaminated, it should be avoided.

Is there a vaccine for viral gastroenteritis?

There is no vaccine or medicine currently available that prevents viral gastroenteritis. A vaccine is being developed, however, that protects against severe diarrhea from rotavirus infection in infants and young children.
