It was a completely different SSRI! I have also tried clomipramine and Prozac, and am on sertraline (Zoloft) now. I have learned meanwhile that the SSRIs are actually drugs with very different chemical profiles if you go into the details. They all do SRI, but after that, the roads depart. This is why trying another SSRI can always help.

I'm not sure what you mean by this. Do you mean that Luvox directly interacts with the 5-HT3 receptor? Or that somehow it interacts more strongly with the 5-HT transporter at synapses with 5-HT3 receptors?
