hey it might be the change in water.do you drink tap water.i've heard that before.when you move to a new place your stomache may not be used to the kind of water there which can cause that.different water will mess your stomach up bad.have you ever heard the saying don't drink the water in mexico.that's why!
Sounds like a nervous stomach or possible IBS, if it continues check with a dr.
try the "BRAT" diet....bananas, rice, applesauce and toast. lots of doctors recommend it. good luck :)
I have also heard that Bananas help with diarreah.
Hard boiled eggs usually stop me up, LOL. Also, get some rice, cook it with chicken broth instead of water. It will "mild down" your system.
eat some chicken noodle soup.. if ur not eating well yes it is going to upset your stomach.
Your body always needs food.
eat some salad or something.. something that is very soft and easy to digest.:)
