Limerence and help with blocking out visualization

I'm committed to this and I've been trying to come up with ways to block out any mental visualization of my LO. We work together, but different divison.

I've visualized her in all situations imaginable, so...

-Photos ... all deleted.

-Sexual ... I use porn at home to substitute and visualize my old-gfs, and an old coworker I won't see again.

-Situational ... I use my last partner LTR.

-Love songs ... I use my last partner LTR.

-Short cuts to her face ... I use my last partner LTR.

I find this to be working well, any other tips??
