Help for Cocaine Addicts in Sight with Drug for Narcolepsy?

From AP:

WASHINGTON - The hottest topic in cocaine addiction is another drug — a medicine already sold to wake up narcoleptics. Hundreds of cocaine users are testing whether that legal pill, called modafinil, could help them kick the addiction, and there's early evidence that it may.

As someone who has watched a few people I really cared about fall into the grips of cocaine, the worst drug I've ever seen in terms of the damage it can wreak very quickly, I'd like to think this might help.
