Chills, Fever Post Burrito - Taco Bell,

I've never heard of anything like this.
I ate a Seven Layer Burrito.
Just 15 minutes later I had severe chills which lasted just ten minutes or so.
The chills turned to what felt like a severe fever. I don't have a thermostat.
This lasted for about two hours.
No related pain.
The finish was really odd. It took only ten minutes to go from burning up to feeling "normal". | Symptoms: Fever, Chills
