Is coffee intake giving me crazy chills?

it’s been about four months where inevitably two or three days out of the week I’ll start getting crazy chills in my body. It feels and by that I mean that my body temperature is very very cold have to basically jump into a very hot shower for and what would normally feel scalding to the touch is the only thing that can bring my apparent feeling of the temperature up enough for me to feel normal. I am partially convinced that coffee is doing this. I did not drink coffee for about a month. Everything was great and I had a large amount of instant coffee yesterday about 2 tablespoons and my symptoms resurfaced.

Has anybody else experienced this, and by that i mean the perceived temperature of your body is lower?

i dont get this as much with diet coke but mainly with coffee

wondering what other agents might be causing this.
