Canadian marathon swimmer Susan Simmons has problems with nausea during the latter half of her longest swims.

Her longest swim to date has been her 70 km double crossing of Cowichan Lake in 32 hours, but she has attempted a 105 km triple crossing.

International Marathon Swimming Hall of Fame Honour Swimmer Vicki Keith gave her some very useful advice to combat her nausea. “Try McVitie’s Digestives. These biscuits are something that I can eat when I am sick on the water. I was pleasantly surprised when I first tried them. They are very easy on the tummy and if eaten before you are sick, they may help keep the sick away.

There’s a bit of science behind the cookies. They have leavening agent that has sodium bicarbonate in it which is an alkalinizing agent that reduces stomach acid. Sodium bicarbonate has also been injected intravenously to prevent motion sickness.
