This technique is credited to Michael Ellner.
Take one hand, and designate it to gather resources. Think of something positive and send those good feelings into the first of that hand.
Then take the thing that bothers you -- maybe it's a craving, or an impulse, or a trigger, and send it into the fist of the other hand.
Practice firing them one by one by squeezing either fist -- better feeling, worse feeling, better feeling, worse feeling.
Then.
Squeeze them both at once.
