At lunch #1 protein style, mustard instead, whole grilled onion, fries and a chocolate shake. Approx 6 hours later started having bloating, stomach cramps, nausea, projectile vomiting, intractable shaking and chills. Lasted for hours with residual symptoms for 2 days. It’s the only thing I ate before symptom onset. | Symptoms: Nausea, Vomiting, Stomach Pain, Cramps, Chills, Headache, Bloating, Shaking
