Upset stomach, no vomiying or loose stool , rather a bit constipated, terrible heartburn . Slight headache and light fever, had a light shiver earlier but better now. Did an 8 hour train trip yesterday, had ghoulash soup on the train??? Returned from Italy where had lots of ice cream, also got a sandwitch at the station in Verona. It all actually sounds pretty clear once describing everything? Took Iberogast, a kind of herbal extract and seems to relieve it a bit. I do suffer from heartburn in general especially after eating pastas and certain grains, also specifically after drinking diet Pepsi but not diet Coke. Thx for help
