Hi Everyone.
While I definitely agree with Aaron that we all have a lot in common and of course we're allways here for each other, I also agree with R. Guard and Yaakov that it's important to realize the differences.
When I was a bochur I smoked for quite a number of years. The reason why I started smoking (weather you believe me or not) is because I thought it would be a good way to calm my nerves. When it was time to look for a shiduch my mother told me that I had better stop smoking because good girls don't like it. At that time I was smoking two packs a day. I cut down steadily for 8 weeks until I was down to one cigarete every three days and then I just stopped.
Being that the only kind of smoking addiction I had was the chemical/neurological addiction it was quite simple to stop with a bit of willpower. Had I had an addictive personality it would have been very different.
Yaakov, don't you agree that if the problem was really the Dopamine, then all we would have to do is wean ourselves of it slowly. Obviously the problem is that we become dependent on it psychologicaly. So what's the difference if we are dependant on dopamine or on overspending. Either way the problem is psychological and not really neurological.
now here's an untested theory as to why. Unlike alcohol or eating which occur in public and are part of an addicts outward life (regardless of the psychology), lust is a private affair, an internal disease. This is why life does not necessarily become unmanageable - outward life continues, it's the inside that's affected. Once recovery begins and the inside begins to heal, there is no urge to act out on the outside. That was never the problem and will not fill the void.
I also have a theory. Lust is a total and immediate escape from the real world. Perhaps a powerful drug could compare. But alcohol doesn't work nearly as fast. On the other hand food addiction and over spending don't give a complete escape at all. They're just a bit of a distraction. There's no way they can take the place of lust addiction. But if someone has an addictive personality, then I guess they would be vulnerable to any sort of addiction.
