I ask that because as you can see from these charts, in terms of impairment, there is not much difference from showing up for work tired and showing up for work drunk:
Weirdly, if you do show up tired from overwork, you may be praised: if you show up drunk, you may be fired.
Regardless, to do good work, you need to sleep. (I know, I should practice what I preach.)
Julia Kirby in HBR has more on this in this piece: Change the World and Get to Bed by 10:00. You’ll be convinced to go to bed earlier by the time you finish it.
