I don't think it is a question of discipline when it comes to addiction - if you are taking it on a regular basis at a high enough dose to become addicted, you will become addicted, and you will have withdrawal symptoms when you stop taking it.

It might be possible to manage the addiction and maybe keep it from escalating with discipline, but the addiction will always be there.

Humans are excellent at denying addiction and rationalizing addictive behavior. And you don't even realize you are doing it - I've seen it in myself with cigarettes, which I fortunately quit years ago.
