A caffeine junkie is someone who is addicted to caffeine and is always jittery, anxious, and on edge, whereas being calm and collected implies the opposite
Consider the statement "I was calm and collected at the thought of seeing Bo, despite all the other chaos in my life.". Based on this "Despite all the other turmoil in my life, just the thought of seeing bo made me like a caffeine junkie." a true statement? Yes, no, or I don't know?
