[QUOTE="_ginge"] During a huge system outage earlier last year I did 4 back to back 19.5 hour days over a bank holiday weekend. Somehow I found it almost impossible to sleep between then..[/QUOTE] I did that during some enormous NMS upgrades for Global Crossing. A day before the scheduled start, they asked for it to be done 48 hours sooner. I did 124 work hours that week.
