I Feel Very Shaky-like I've Consumed 20 Cups Of Caffeinated

I feel very shaky-like I've consumed 20 cups of caffeinated coffee, I'm also nauseous, dizzy, and when I'm up walking around, it feels like a little pressure in my chest. I checked my blood sugar and it's 106-absolutely normal. But it does feel a little like a "low sugar" attack.
