Yea I would say it's a core characteristic =), not all encompassing. Many codies weren't looking to suppress emotions, somehow they got sucked in to it and ended up suppressing after the fact.
I didn't count bottles or call her job. I did smaller things like paying attention to her breath, noticing empty bottles in the trash when I went to throw something away. I started catching on and the lies became so ridiculously easy to spot. Once I put all the pieces together the relationship ended fairly quickly. I know myself better now and have fail safes in place to not let this happen again. The universe was going to keep dishing these relationships till I figured it out.
Please share your key with NPD and the ACON side of things.
