Spicy Chicken Sandwich Illness - Carl's Jr,

Had a spicy chicken sandwich with tomato and onion plus fries. 3hrs later stomach is cramping in agony and have diarrhea and nausea. Could not sleep. This is not the first time at this location. I am more often sick from their food than not, it seems. I don't understand why as I have a strong stomach. Makes me VERY suspicious of their food :'( in pain | Symptoms: Diarrhea, Nausea, Cramps
