There is a rare syndrome that is becoming more common as cruising increases. A person takes month or year to get their "sea legs" back after a cruise, boat ride, or even an airplane trip. Many of us have had this syndrome for years after taking a cruise. If you feel a rocking, swaying, or bobbing motion, imbalance, and fatigue and have difficulty concentrating every day, all day, you probably have this.
This is called Mal de Debarquement Syndrome (MdDs). If you need information email me or contact http://nhffoundations.net
or type in Mal de Debarquement into Google. A lot of people feel like they are going crazy when the rocking doesn't stop for weeks or months and this actual effects your ability to think and speak for most people, in some degree. We are trying to increase awareness of this syndrome and let people know what they have. I have had this for over two years after a cruise. I have had other shorter episodes after boat rides and cruises.
It is true that other types of vertigo are similar to this syndrome, but many doctors have never heard of this. Most of the people in our support group (yahoo) self-diagnosed and had to print out Medical articles (Dr. Timothy Hain) to take to our own doctors. I am just trying to get the word out that there is such a syndrome for the people who are struggling with this. I had this after my first cruise for 1.5 years; it went away in one day. I went on a 2nd cruise 6 months later and now have had it 24/7, for 2 years and 4 months, not fun. We have over 100 people in our support group and some have had it over 14 years. They cannot work or function normally. Some drugs are helpful for different people. But it helps to get ideas on treatments and coping skills.
