Which way will you get better faster?
This is a sickness. Yes, it's a sickness that involves an aveirah, but right now, you're limited in what you can do about that, until you treat the sickness. So your goal (as far as your avodas hashem goes) HAS to be to focus on dealing with the addiction (see the handbooks for that). And your growth in terms of avodas hashem MUST be measured in terms of how well you're dealing with the addiction, not how often you've done the actual aveirah. And the reasoning is simple - which way will get you better faster and more effectively, to get you away from this aveirah for good?
