Double Bacon Burger Illness - McDonald's, Le Gosier Grande-Terre

Le Gosier, 97190 Grande-Terre, Guadeloupe

I went to Macdo du Gosier at 11:35pm after my order (Best of Double Royal Bacon), my last meal before that was at noon, and I had drunk a fresubin (a high-calorie drink around 6 pm) you should know that I very rarely have digestive problems.
But about 1 hour after eating this burger I find myself having a huge stomach ache then feeling nauseous and vomiting, I squirtle in pain all over the place.
A moment later the pain subsides, I fell asleep around 2 am then, not surprisingly, at 3 am I woke up in pain, I have a huge diarrhea. Followed by stomachaches until morning.
Thank you McDonalds, Sincerely a customer who will not return to you | Symptoms: Nausea, Diarrhea, Vomiting, Stomach Pain
