Yeeeeaaahhhh... this is not unusually something that bounces day to day within a week's schedule.
And on 3 occasions, I've worked an "overclopen" shift: 8pm-7am day 1, 3:30p-10:30p day 2, 7a-4p day 3.
Not a lot of sleep happens then, since there's 2-3 hours of commuting tucked between each of those shifts.
