Dark Craving

The  is an Addiction in Fallout 4.

Dark Craving is a negative status effect inflicted upon the Lone Wanderer while in Survival mode. The effect is gained when you feed upon a corpse to satiate their hunger. Food will no longer sate hunger; the player can only commit cannibalism to fulfill hunger requirements, and will go straight from being satisfied to being very hungry instead of the intermediate statuses (peckish, etc). The game treats this as an Addiction, which can be cured by any doctor NPC for 75 caps. This will appear as a dialog option. Addictol or Refreshing beverage will not cure the addiction.
