Intense Pain Post-BK Meal - Burger King, Thillois Grand Est

Parc Millésime, Thillois, 51370 Grand Est, France

It's 4:00 in the morning, I ate around 19:00. I had trouble digesting, and since about 1 am, I have been suffering from severe pain in my intestines, I have been sick for 3 hours in a row.
Also note, that the onions were huge in the burger, not even cut. ANYWAY. 2 times I go, 2 times I'm sick.. it's over for me. | Symptoms: Nausea, Diarrhea, Stomach Pain
