It takes at least 21 days to replace a negative habit (this includes negative thinking patterns and emotional responses).  Detoxing your will requires first being aware of a choice or decision that fuels a negative habit and then starving it!  The following Cherokee proverb will illustrate what I mean:

An elderly Cherokee Native American was teaching his grandchildren about life...

He said to them, "A fight is going on inside me, it is a terrible fight and it is between two wolves.  One wolf is evil -- he is fear, anger, envy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, competition, superiority, and ego.

The other is good---he is joy, peace, love, hope, sharing, serenity, humility, kindness, benevolence, friendship, empathy, generosity, truth, compassion and faith.  This same fight is going on inside you, and inside every other person, too."  They thought about it for a minute and then one child asked his grandfather, "Which wolf will win?"

The old Cherokee simply replied: "The one you feed".
