What happens if a crewmember wakes up halfway to Mars? Does that affect energy/mass budget? What if they all wake up halfway there?

For our baseline habitat, the consumables for both the transit phases as well as the contingency stores are based on the required TPN dosage for a resting state. We did not take further reductions to account for the lower metabolic state associated with cooling. Thus, the habitat is designed for the off-nominal situation of a conscious crew.
