Add a new bullet to the list of Emotions:-

• Alert, Tired, Fatigued, Exhausted

In the rule “Emotions”, add two new paragraphs before the paragraph beginning “If a single Emotion”:-

“Increasing” an Emotion means replacing it with the Emotion immediately higher than it within the same Nature; “decreasing” an Emotion means replacing it with the Emotion immediately lower within the same Nature.

If a Crewmember is not Tired, Fatigued or Exhausted they may gain the Alert Emotion. A Crewmember may decrease their own Emotion of Alert, Tired or Fatigued to increase or decrease any of their Emotions that has a different Nature.
