DMSI 3.3.2, OED, X124, PSEv3, etc.

[Shannon]

Guys will tend to become responsive to the DMSI aura being projected from a straight man by respecting him more and wanting to be in his good graces, unless that DMSI user appears to be a threat to his relationship.  After a while, you tend to normalize the effects and see them better only when you stop using it.

That makes sense about the guy I assisted. 

I suppose that the 'normalize the effects' phrase means that I get used to them and see the effects better in contrast? Or do they get more noticeable when you're not running the sub anymore?

Your brain is a differencing engine, so you notice best what has the most difference from what you have around you.  If you're just getting used to the effects, you should notice a significant difference if you stop using it for a month.  If you are no longer executing the same, you should notice no such or much less such difference if you stop using it.
