A British woman who went on a two-week dream cruise to Hawaii continues to suffer from sea sickness five years after the trip.

Doctors are unaware of what causes the condition or how to treat it with many patients often spending years together in search of a correct diagnosis. Michele-Marie underwent MRI scans and was tested for various conditions, including multiple sclerosis, before doctors at the Royal Berkshire Hospital arrived at the correct diagnosis six months after her cruise.
“I have days when I feel sorry for myself and there are days when I wake up and I wonder if it's gone away. But then it says, 'da-da - here I am’. It's like the disorientating feeling you get after coming off a waltzer at the fair - all the time. It's horrendous”, she said.
