I know I've worked a couple of 100+ hour weeks, both containing 48 (or more) hour "days" where I was working without sleep. This is back when I used to do tech work for events and I had to babysit the setup. That's a 7 day week though, not a 5 day....and those circumstances were rare.
Longest stretch I ever worked was 56 hours, over which I got about an hour and a half of sleep. I started Weds morning at around 9am or so and didn't finish until Friday afternoon.
Prior to that job, the most I probably ever worked and was paid for as an hourly employee was maybe 80 or 90 hour weeks, again...all 7 days.
