Upset stomach

Anyone got any ideas for something to calm an upset stomach? Nothing serious. I just get a little queezy now and then. I am eating every four hours and drinking all the other time. It's stress stomach. I have always had it. Just wondering how to calm it now. Used to use 7-up or pepto if it was bad.

I know it sounds weird but I had someone suggest salt. I had nothing to lose at that point and tried adding some to my solid food and it really helped. I hope this helps.
