A foundational approach to the treatment of addiction is to increase opioid levels in the brain through natural and non-invasive means, and thus reduce cravings. Below is a link to a little book that outlines simple cognitive procedures that can provide for the sustained elevation of opioids as well as dopamine in the brain. It is based on a rather obscure fact in affective neuroscience that mid brain opioid and dopamine systems stimulate or potentiate each other, and the resulting premise that their mutual activation through simple cognitive means will increase both these neuro-modulators and resulting affective tone, and will do so far more than if those systems were activated alone.

My argument and the procedure that follows (pp. 28, 39-41), is novel, short, succinct, simple and easily testable, and was written in consultation with and with the endorsement of Dr. Kent Berridge of the University of Michigan, a leading authority on the neuro-psychology of addiction. The book is written in two parts, for a lay and professional audience. Since the procedure is simple and innocuous, you may find it worthy of trial.
