Short answer: it depends on which stage you are in. Rocking that starts after a cruise, flight or long drive and fades within a day or two is common land sickness. It becomes mal de débarquement syndrome (MdDS) only when it lasts more than 48 hours. After that, the Bárány Society criteria call it transient if it resolves within one month and persistent if it lasts longer. Persistent MdDS can go on for months or longer, which is why the one-month mark is when an evaluation matters most.
How long does mal de débarquement syndrome last? The 3-Stage MdDS Timeline
The timeline below follows the diagnostic criteria published by the Bárány Society (Cha et al., 2020, Journal of Vestibular Research). It is the same framework a vestibular clinician uses to decide what you have and what to do next.
| Time since the trip ended | What it is called | What it typically feels like | What to do |
|---|---|---|---|
| First 48 hours after the trip | Land sickness (common, not MdDS) | Rocking or swaying after a cruise, flight or long drive that is already fading | Stay active and keep your normal routine. It usually settles on its own. |
| 48 hours to 1 month | MdDS — in evolution, or transient if it resolves by 1 month | Rocking, bobbing or swaying most of the day; often eases while riding in a car | Keep a short symptom log. Get evaluated if it is not easing, or if it is disrupting work or sleep. |
| Longer than 1 month | Persistent MdDS | The same rocking sensation, often fluctuating; may flare with stress, poor sleep or another trip | Get a vestibular evaluation. Rule out other causes and start a structured home program. |
Is it normal to feel like you are still on the boat after a cruise?
Yes. After hours or days of motion, the brain adapts to the movement, and it can take a little while to switch back once you are on solid ground. That brief rocking feeling is common and usually fades within a day or two. On its own it is not a disorder.
When does rocking after travel become MdDS? The 48-Hour Rule
Under the Bárány criteria, four things point to MdDS:
- a rocking, bobbing or swaying sensation present all or most of the day;
- it began within 48 hours after passive motion ended (a cruise, flight, train or long car ride);
- it eases temporarily while you are back in motion, such as riding in a car;
- it has lasted more than 48 hours.
That third point surprises people, and it is one of the clearest clues. If you feel steadier in a moving car and worse as soon as you stop, tell your clinician.
How long does persistent MdDS last? The 1-Month Mark
Once symptoms pass one month, MdDS is classed as persistent. Persistent MdDS does not follow one fixed timeline: it can last months or longer, and it often fluctuates, with better and worse stretches. Many people notice it flares with stress, poor sleep or another trip. Because it is rare, it is also often missed, and people may see several clinicians before anyone names it.
This is the point to stop waiting it out. An evaluation confirms the pattern, rules out other causes of imbalance, and gets a structured plan started.
Can MdDS come back after it goes away?
It can. Symptoms may return or worsen after another cruise, flight or long drive. If you have had MdDS, it is worth talking to your clinician before a big trip about how to plan it and what to do if symptoms return.
What helps while you are in the first month?
- Keep moving. Stay with your normal daily activity as much as symptoms allow.
- Keep a short log. When the rocking is worst, what eases it, and whether riding in a car changes it.
- Note your history. The trip that came before it, and any history of migraine, both shape the plan.

Red flags: when rocking is not MdDS
Call 911 if dizziness comes with sudden weakness or numbness, slurred speech, double vision, trouble walking, a severe headache, chest pain or fainting. Sudden hearing loss in one ear needs a doctor the same day. Constant spinning with vomiting, or dizziness that keeps getting worse, also needs prompt medical attention rather than a wait-and-see approach.
Getting evaluated for MdDS by video in New Jersey, Ohio, Georgia or North Carolina
MdDS is diagnosed mostly from your history and how your balance and eyes respond to movement, and the treatment is a home program that is coached and progressed. That makes it well suited to telehealth. Dr. Rob Letizia, PT, DPT sees MdDS patients at our clinic in Wayne, New Jersey and by video for patients in Northern New Jersey and across New Jersey, Ohio, Georgia and North Carolina. Read more about how MdDS is treated, or see how telehealth vestibular therapy works.

What it is, what treatment involves, and what to note before an evaluation — from Dr. Rob Letizia, PT, DPT.
Vestibular rehabilitation is exercise-based, so much of it can be delivered over video — the diagnosis comes from watching your eyes and head movement, and the treatment is a coached, progressed home program. Dr. Rob currently treats telehealth patients located in New Jersey, Georgia, North Carolina, and Ohio.

Common questions
How long does mal de débarquement syndrome last?
It depends on the stage. Under the Bárány Society criteria, MdDS is diagnosed only when rocking or swaying that began within 48 hours of passive motion lasts more than 48 hours. It is called transient if it resolves within one month, and persistent if it lasts longer than one month. Persistent MdDS can go on for months or longer and often fluctuates.
Is it normal to feel like you are still on the boat after a cruise?
Yes. A brief rocking feeling after a cruise, flight or long drive is common and usually fades within a day or two. It is only considered mal de débarquement syndrome when it persists beyond 48 hours.
Why do I feel better in the car when I have MdDS?
Symptoms that temporarily ease while you are back in passive motion, such as riding in a car, are one of the defining features of MdDS in the Bárány Society criteria.
When should I see someone about rocking after travel?
If the rocking has lasted more than a month, or is disrupting work, sleep or daily life sooner than that, get evaluated by a clinician experienced with vestibular disorders. Seek urgent care right away for sudden weakness, slurred speech, double vision, a severe headache or sudden hearing loss.
Can MdDS be treated by telehealth?
Often, yes. The evaluation relies on your history and on watching your eyes and balance on camera, and the treatment is a home program. Dr. Rob Letizia, PT, DPT sees MdDS patients by video in New Jersey, Ohio, Georgia and North Carolina, the states where he is licensed.
