About 10 Days Ago, I Had Severe Indigestion Symptoms Which

About 10 days ago, I had severe indigestion symptoms which lasted about 6 hours. I had eaten a chopped salad with cabbage and other raw vegetables and attributed it to that. Since then I've had this sense of fullness and am only eating very small portions at a time. I can have a bowl of cereal in the morning and still feel stuffed hours later.
