Hello! Happy New Year! Girls, this is crazy, I have a big problem. Yes…

Hello! Happy New Year! Girls, this is crazy, I have a big problem. Yesterday I ate anything and everything, and today since 4 am I started having stomach upset. Watery diarrhea, I was running through every couple of minutes at night. A large fluid loss in the body occurs. I feel like everything's fermenting in my body, constant burping in my stomach. To replenish the lost fluids, I drink water. I also eat bananas, I haven't eaten anything else. What should I do in this situation? I feel absolutely normal, no symptoms like with diarrhea, everything is fine, but only the stool bothers me very much. Who has encountered such a problem, what did they do? I already wrote
