"having a handle on the lusting is proving to leave me with enough energy, which can be more profitably used elsewhere".
Please consider that you are really only recognizing the tip of the iceberg when you say this. It is much, much more than a waste of your precious energy. It is actually deforming and poisoning every aspect of your life with self-centerdness, disproportional comparisons and irrational thinking.
If you take hold of the steps and actually work them the way your sponsor did, get a sober chevra to stay sober with (preferably alive and talkable, like in a meeting) and make calls as needed, your chances are really good.
