Multiple Foods, Severe Symptoms - Reese's,

I ate a bagel sandwich from Big Apple Bagel (turkey, lettuce, cheese, blueberry bagel) at around 11:30. I then ate a Chipotle burrito (barbacoa, pinto beans, brown rice, cheese, and lettuce) at around 2-2:30. Then I ate a reese's vanilla McFlurry from McDonalds at around 3:30, but my friends ate Oreo McFlurries without any symptoms. I started having some voluminous gas around 6-7 and then it gradually degraded into continuous stomach discomfort, frequent diarrhea (lasting until now, 4:20 am, but continuing until who-knows-when). I puked 6 times in a row around midnight, and temporarily felt better, but I'm back to feeling like vomiting is a possibility again. | Symptoms: Diarrhea, Nausea, Fever, Vomiting, Gas
