Yes, there is a 'less is more' thing going on with -mones. Two much and the receptors, in a sense, shut down. I think the term 'ghosting' comes with this. As in, because of the shut down, you are no longer visible to the other person. Which is a subset of ODing.

The amount of -mones you are using is too much. For me, 2 sprays of C7 is golden. Anything more is counterproductive.

Take a few days break to come down to normal levels and start up only using small amounts. It's painful to start slow, but it is a necessity. One spray C7, then two, back down to one, etc...

Also, hits are mostly subtle. For example, the girl next to me in class (in a tech lab at computer stations) when talking I looked something on the web about the topic of conversation and she leaned in real close to read the screen. Knowing her for two months now this is not normal (she was kissing close). That particular day I was wearing a super mix (tons of SoE, AE, A314). It's up to you to notice those subtle changes in people. Sometimes it's a door opening wide with a friendly person greeting you and other times it's a window cracked gently open.
