No, it's not at all, and you're not wrong to generalize in this case. For me, emotional energy is pretty boundless except as linked to physical energy, which eventually wears down. In one week of a hypomanic state I might run three marathons and sleep twelve hours. In my first drug-assisted state (I was originally put on paroxetine for depression, which apparently forces me into a hypomanic state) I slept three hours over a period of 10 days. That's not sustainable!
