Caffeine and Other Co-Factors\u003c\/h3\u003e\n\u003cp\u003eMany beverages sweetened with monk fruit also contain caffeine (such as diet sodas, energy drinks, or flavored coffees).

These symptoms often improve over days to weeks as your body adjusts to a lower-sugar pattern.\u003c\/p\u003e\n\n\u003ch3\u003e5. Dehydration and Electrolyte Imbalance\u003c\/h3\u003e\n\u003cp\u003eWhen people start reducing sugary drinks, they often unintentionally drink \u003cstrong\u003eless total fluid\u003c\/strong\u003e or replace them with caffeinated options. Mild dehydration can easily show up as a headache.
