The day after eating cereal I wake up exhausted. My abdomen, back ribs and chest are sore to the touch. I feel as though my intestines are irritated and swollen and that my digestive system slows down. I've stopped eating cereal but am curious to see if anyone else experiences similar symptoms, mostly the tender abdomen. I've tried to think if its the wheat, the milk product (in the cereal... I eat cereal with almond milk and water), or the fructose. I only experience the tenderness with cereal, nothing else.
