The way to build self-trust, Dr Marc Lewis explained, and get over an addiction is for the addict to begin an internal dialogue with his future self to convince his present self that it can, in fact, live without its addiction. Lewis finished by explaining how he did just that. By writing the simple word 'NO' on a piece of paper and reading it at every moment he had a craving, he gradually started believing that if he could cope a few hours without drugs, then he could cope for a few days and, eventually, for good. He pleads that the only real way to help addicts is to motivate them to place their trust in themselves and to encourage them to engage in their own positive internal dialogue.

Interesting argument to "handing over your power?"
