A closer look

You aren't just addicted to the caffeine; your brain is fundamentally rewired by the aroma. Studies on sleep-deprived rats (which is basically the scientific equivalent of a human Monday morning) showed that just inhaling the scent of roasted coffee beans activated proteins linked to stress relief and antioxidant defense in the brain. So yes, aggressively smelling your morning brew is legitimately a neuro-chemical coping mechanism.
