Bad dopamine hygene is a serious thing that should get more focus.

But MDMA is seritogenic, not dopaminergic, and bad serotonin hygene is predominantly a too-little problem and not a too-much problem (unless you're using drugs, then you've got to regulate both ways).

Nobody's complaining, so far as I know, that having too many socal connections is degrading their capacity to enjoy a cup of tea in solitude.
