|I don't have a wife, however your situation is very recognizable.
The shower often gets me waked up in the morning after a poor night sleep. I usually go to bed at set times, however when I'm working on a hard problem my brain doesn't stop working. This results in a restless night that doesn't give me the feeling I slept well.
Food does tend to get problematic too, mostly because I eat late when I have a deadline.
What about weapons of mass-construction?
