Just drank entire blender of cold smoothy (frozen banana, cool apple, frozen kale, spinach, and chard). Prior to that I ate 1/4 cup salmon and 1/4 cup quinoa. After drinking the smoothy, I started shivering to the point of my teeth chattering. I m drinking some hot tea now, but I m still shivering. Could this be caused by not getting enough carbohydrates?
