Addiction

From Edge of Darkness Wiki

Addiction (Flaw) :

Your character is hooked on a certain substance or behavior. If he doesn't get it regularly, he gets anxious and goes out of his way to satisfy his need, even neglecting more important duties. If he goes three or more game sessions without indulging this addiction, he is assumed to have beaten it (your character loses the Flaw). The Storyteller is free to inflict harsh withdrawal symptoms, however.

Note: Satisfying this particular addiction does not count as indulging a Vice such as Gluttony. No Willpower points are gained for doing so.
