Insanity

Identify the purple bar

The purple bar is Insanity. It is separate from the blue Zzz effect Lack of sleep and the energy bar. Work can raise it, and its tooltip explains that alcohol or good sleep can reduce it; sleep has this effect when you are tired.

Berry Pie

Choose a consumable

Without bonuses, Beer changes insanity by −12 and does not restore energy. Berry Pie restores 30 energy and changes insanity by −3. Existing effects and perks can modify these values; read the current item tooltip rather than treating every food as an insanity cure.

1. Check all three indicators before a long crafting or gathering trip.
2. Sleep at home when tired. If the blue Zzz remains, continue resting until the effect clears.
3. Bring energy food and a suitable insanity consumable separately. Zombie can handle repetitive production after you build its supply and transport chain.
