From childhood…
My mother gave us flat ginger ale for nausea when I was a kid. I also remember ginger ale in the hospital for nausea. (of course both memories are from the last century)
When I felt nauseous during a Woods hole training a few years ago, one of the coaches gave me dried ginger which settled my stomach.
I now always carry ginger in some form as part of my kit in the day hatch. I always have crystalized ginger in hand. I have come to like “instant Ginger Honey Crystals” My favorite ginger ale is a packet of these in a glass of club soda.
