Unfortunately most of the drugs you're talking about are called different things here in New Zealand, but as to the question of the title, mood stabilisers and anti-depressants can be mixed quite effectively. I'm bipolar II, my shrink has me on 60mg Citalopram (aka Celexa) and some lithium to augment it. It's definitely doing something, although it's not doing enough, but we're still tinkering with the dose a bunch.
