Do We Have This One? I haven't seen it anywhere.

In Real Life, breaking free of a drug addiction is a lengthy process--it takes months and requires medical supervision. In fiction, however, people routinely overcome their substance habit by going through a single self-imposed (and often painful) withdrawal phase, after which they are no longer addicted. Frequently involves locking oneself up in a room or chaining oneself to a bed.
