Severe Symptoms After Meal - McDonald's, Leucate Occitanie

300 Rue Dali, Leucate, 11370 Occitanie, France

I went to this place on Monday evening, having a big craving I had a signature menu for €15 with bacon and Savoyard cheese.
I ate my meal quite quickly and ten minutes later I had a very strong stomach ache and the meal came back up.
So I decide to vomit but the pain persists.
From that moment on I spent an abominable night, vomiting all my food until I vomited bile.
This was followed by intense dehydration mixed with fever and dizziness. Since I couldn't drink because I vomited everything I swallowed, I had to wait until 5 am to have a drink which I then vomited.
Occasionally a small diarrhea that is very dark in color and completely liquid.
Very bad experience! And I can confirm that this is where this drunkenness comes from because I hadn't eaten anything for a few days.. | Symptoms: Nausea, Diarrhea, Vomiting, Bile, Fever, Dehydration, Dizziness, Stomach Pain
