I’m studying for a physiology exam and I feel like I’m shaking. I don’t know if it’s because I’ve had too much coffee or not enough. Or maybe because I haven’t eaten since breakfast. Should I have more coffee or should I have some mango juice because I have a can of mango juice in front of me and I haven’t finished it yet but it’s still cold! Or maybe I should get up and get something to eat. But I’m studying -____________-
