Here is the brutally honest, not-funny-but-I’ll-make-it-funny answer: Drink flat, room-temperature Coke only if you have indigestion from overeating and have no access to real medicine. The phosphoric acid might kick-start digestion, and the burping might help.

But skip the Coke if you have: nausea from the flu, a hangover, acid reflux, or a stomach virus. In those cases, Coke is the equivalent of pouring battery acid on a papercut. Stick to water, clear broth, or that magical elixir known as Ginger Ale (which, hilariously, often has less actual ginger than the promise of a politician). Or, you know, an actual ginger root.
I once tried the Coke cure on a dodgy burrito. I spent the next hour sitting on the cold bathroom floor, whispering apologies to my ancestors. My friend, who swore by the method, watched me suffer and then said, “Maybe you need the Mexican Coke—the one with real sugar?” I swear, some people would trust a puddle with a map to the lost city of gold.
Bottom Line: It’s a Gamble, Not a Guarantee
The “Coke for upset stomach” myth persists because, for a very specific type of stomach ache (the “I just ate a brick of cheese and regret it”), it can feel like a miracle. But for everything else, it’s a con. It’s the siren song of the soda aisle, luring you in with fizz and sweetness before crashing your ship into the rocks of regret.
So next time your tummy acts up, ask yourself: “Am I a bezoar-containing medieval peasant, or am I a modern human with a possible acid problem?” If the answer is “modern human,” put down the Coke. Grab some water. Lie down. And remember: you are stronger than the temptation to bathe your digestive tract in liquid candy and phosphoric acid. Probably. Maybe. Okay, fine—go ahead and try it. But don’t say I didn’t warn you when you start communicating with the toilet in a language of pure pain.
