I was always told that if you have a upset stomach or a tummy problem have a few sips of whiskey does it actually do anything to help?

Probably Not: Liquor is likely not good for a stomach when ill. Many cultures recommend different home remedies. The treatment ultimately depends on the reasons for stomach upset--too much acid, infection, ulcer--but again, liquor will almost certainly not help the vast majority of stomach pain causes. And in fact, it will likely make things worse.
