I added something I learned from Stellar Wind and the torture struggle. When someone is tired, their judgment can be impaired. When they are dragging, it is hard for them to float above a problem and picture themselves and the problem in another place and time, so I gave them another directive: sleep. When you sleep, your brain is actually engaged in the neurochemical process of judgment. It is mapping connections and finding meaning among all the data you took in during the day.
