My husband ate 2 double cheeseburgers and has been sick since. It started slow with nausea, then vomiting all night, Had to take the day off from work and he now has fever and chills and is still weak and lightheaded. He has finally stopped vomiting. I told him not to eat there. I never eat Mcdonalds. | Symptoms: Nausea, Fever, Vomiting, Weakness, Chills, Lightheaded
