(0:25 hours)

I really thought I wouldn't sleep for this one! When I got to work I was really tired, but someone opened the window and the breeze perked me right up and by lunch time I felt very alert.

I drifted for the first half of the nap, and woke up after 10 minutes and just had to look at the clock. It said 15 minutes remaining so I went back to sleep and fell asleep straight away.

When I woke up I felt the best I have felt after any nap so far.
