Too much unhealthy. Food. I would feel the same had i eaten what you describe. Try antacids, fluids. And do not be such a devouring eater. Exercise!
Watch diet . Eating half bag of chips soda then goldfish? Expect upset stomach. Your diet should be watched closely for things you can tolerate as you age.
