> I keep hearing about people being on Wellbutrin and also Zyprexa at the same time. This doesn't really make sense to me, as the two are cancelling each other out? Wellbutrin as most may know inhibits the reuptake of dopamine and norepinephrine, in effect increasing the levels of these neurotransmitters in the synapse.

>i'd imagine zyprexa's affinity for different receptors to not be the same ...
i.e. those that it has the most affinity for are probably most responsible for its therapeutic effect...
the additional dopamine/norepenephrine can go to the receptors that need it more (and are antagonized less)
just guessing
