Change Your Setpoint
http://gettingstronger.org/2010/10/change-your-setpoint/ is about weight control, but it is very, very relevant. It's also heavily fact-laden and thoroughly researched. It's good reading for anyone struggling with any addiction.
Although my alcohol addiction is broken, I am still working on becoming a nonaddicted person overall. Cross-addiction is pretty common. Whether we believe in the dopamine/serotonin-related theories, the "hungry heart," the addictive personality, something else, some combination (they're not mutually exclusive, and some interact), the empiric fact is that people who hop off of one runaway train may find themselves on at least a fast-moving horse.
Junk food isn't the worst addiction. It's better to be fat than to be jailed/fired/etc. I'd rather be none of the above, though.

The pleasure budget. The receptor control theory goes beyond weight management to explain more generally the regulation of pleasure in your life. If you have ample dopamine receptors, then a wide variety of stimuli– including food, social interactions, work, and other interests– should provide you with sufficient pleasure to make life not just bearable, but interesting. However, if you end up with an undersupply of dopamine receptors — whether it be from birth, addictions or unremitting stress — then your baseline pleasure “set point” will be low and you’ll be vulnerable to depression, low self-esteem and other aspects of unhappiness. Addictive escapes may provide temporary (but unsustainable) bursts of dopamine, serotonin, and other feel-good neurotransmitters, but at the cost of further downregulating dopamine receptors and feeling worse later on.
This is fairly close to my evolving paradigm as it currently stands. I was born two drinks below par (as people used to say). My unpleasant early years were harder to take and harder to shake because my wiring didn't allow for happiness via normal channels. My instinctive attempts to fix the problem with addictive substances actually made it worse. The Sinclair Method forcibly broke the direct alcohol addiction, which is totally awesome and was a necessary prerequisite before I could take any other measures, but it didn't fix the original problem of being two drinks below par.
