Here is a report from a court case in Ireland which has relevance;
Drink of Coca Cola caused crash
Galway driver David Colleran (27) made the national news when he appeared in court on a charge of careless driving in the city late last year. Mr Colleran told the court that he suffered a "vaso-vagal attack", brought on by drinking Coca Cola. This, he said, caused him to lose consciousness for a brief period, with the result that his SUV crossed the road into two oncoming cars. A medical report linked the pain experienced by Mr Colleran to the gas in the Coca Cola. Judge Mary Fahy acknowledged that fizzy drinks have been known to cause some people to feel faint, but convicted the accused of careless driving and fined him €250.
I eat when I'm hungry and drink when I'm dry and if the moonshine don't kill me I'll live til I die.
