Yeah, Prozac acts on the 5-HT2C receptor (as well), i'm pretty sure. But remember part of what could contribute to its anxiogenic and more or less stimulating type of effects is that its metabolite... duloxetine, i believe (as opposed to Prozac/fluoxetine)... is a NRI-- and one with a significantly long half-life, if i'm not mistaken.
Also, do you know, does it pretty much sound like overall consensus here that Zoloft does have qualities different enough than other SSRIs in a way that feels like a dopamine reuptake inhibiting effect? That would be interesting because, yeah, the experts seem to think that its effect on the DA transporter would be negligible in terms of subjective effects.
Also, does Strattera really act on the kappa opioid receptor? I never heard that. That's really interesting if so.

Also, the Prozac-induced anxiety (5-HT2C agonism? I can't remember which receptor subtype) starts to overwhelm the positive effects as well, and I become a nervous idiot in social situations.

Prozac at the NE transporter, Zoloft at the DA transporter, (Strattera at the kappa opiate receptor...not a SSRI, but still), Lexapro doing...something sleepy... all of these things are /supposed/ to be clinically insignificant, but those of us who have tried these drugs know they're not.
