I am the kind of person who gets nauseous watching 3D movies, or those with shaky-camera movements. I can't read or text on my mobile phone while in a moving car or train.
And if I'm in the passenger seat and we are driving uphill, the driver needs to drive really, really slowly or risk having to do some massive cleaning up in the car later.
So, I was initially a little worried about the idea of spending eight days "stuck" on a cruise ship. It was to be my very first cruise. What if I got seasick?
Luckily, my mother, who also suffers from the same condition and who came along with me on the cruise, had brought along a seasickness prevention kit - stocked with everything from pills to wristbands.
But after doing a quick Google search on the Royal Caribbean's magnificent Mariner Of The Seas, I felt better because such a huge ship was unlikely to make me seasick, surely?
As it turned out, I was right. Even for such a motion sickness-prone person as me, the experience on board was nothing short of amazing.
The only time I ever felt slightly seasick was when I was sitting by the glass windows in the dining area which overlooks the sea.
Speaking of the dining area, the food served on the ship was the highlight of my entire experience. The Singaporean "uncle" I met during check-in said it was his second time on the Mariner Of The Seas.
And then his eyes lit up as he said: "Oh, I come here mainly for the food-lah ... it's very good!"
They serve a massive buffet spread for breakfast, lunch and dinner at the Windjammer Cafe on the ship's 11th deck.
There's amazing variety, from Western-style salads, mashed potatoes burgers and baked pastas to Indian briyani, fish and chicken curry, and mouth-wateringly good desserts (with different varieties each day).
Food and beverage director Christophe Poitevin said the food served onboard is specially created depending on the guests' nationalities.
"This time, we had an international crowd, so we had to customise the menu to suit our guests," he said.
Poitevin, who is from France, manages 650 staff members - that's more than half of the ship's 1,200-strong workforce.
According to executive chef Kenneth Johansen, the most popular dish, on any of their cruises, is always the seafood.
"Seafood is always a winner, anywhere in the world - whether in China, the United States or in Europe," said Johansen, who has been with the company for over 11 years.
The best thing about the food onboard is that almost everything is free, apart from the alcohol in the bars and the food offered by a few specialty restaurants.
There is another cafe on the fifth deck, called the Cafe Promenade (open 24 hours), which serves delicious pizzas, sandwiches, pastries and cakes. I'll never forget that glorious, melt-in-your-mouth cheesecake stick.
