This has been the busiest week I've ever had at work, by a pretty wide margin:

Monday: 9:30 AM - 12:30 AM (15 hours)
Tuesday: 10 AM - 9:30 PM (11.5 hours)
Wednesday: 10 AM - 11:30 PM (13.5 hours)

That's 40 hours of work in 3 days. That might be normal for a consultant, but certainly not for me.

And yes, I've been working most of those hours.
