One of the remedies your mom used to have for tummy aches was ginger ale because ginger ale is known to soothe your tummy. Apparently, ginger ale makes things worse according to Delish!
Think about it this way - there is a whole lot more sugar in ginger ale than ginger which is why you feel sicker!
When you feel sick, try something like Gatorade or clear liquids, even crackers but stay away from ginger ale!
