Mania:

Owen Scott Muir:

"Mania is a state—in a time-limited period—where someone acts differently. This can range from a little different to “completely bonkers” different. It’s in the direction of “more”—more energy, more volatile mood, more enthusiasm, more grandiosity, more irritability, more sex, more drugs, more rock and roll, more spending, more wakefulness. The only things that we get less of are sleep and good sense."
