Cruise secrets: This unlikely location is the best place to go to beat seasickness

“’They don’t want to compromise the roulette ball. Nor do they want any seasick passengers heading back to their cabins and interrupting a losing streak.

“’If you’re feeling queasy on board then Kieran reckons the casino is the only place to be.’”

In the absence of a casino – and according to the NHS – other advice includes breathing fresh air, looking straight ahead at a fixed point, such as the horizon and close your eyes and breathing slowly while focusing on your breathing.

The NHS also recommends trying ginger “which you can take as a tablet, biscuit or tea.”

However, Doctor Ben MacFarlane reveals in his book that medical staff will most likely know if you’re using seasickness as an excuse for a hangover.
