Okay, let’s get slightly serious. Waterborne illnesses are real, even if you drink from a clean tap. A bug like giardia or norovirus can linger in your system, and your stomach becomes hyper-sensitive. So just a glass of water can trigger a full evacuation. It’s like your body is on high alert, treating every sip like a threat.
If you also have cramps, diarrhea, or a low-grade fever, you might be dealing with a little microbial stowaway.
