> To be clear, the feeling of being on top of the world and superhuman is hypomania, and not full blown mania (hypo indicating "less than" mania)

Which, unrelatedly, always confused me. "Hypo" in medicine usually means "a dangerous lack of something"--hypoxia, hypothyroid--not "too much of something, but not way too much." The first time I heard "hypomania," I assumed it meant depression! It seems like "semi-manic" or something along those lines would have been clearer.
