I know it's been awhile since your post... but it's not like the issue goes away, so I'm going to answer your question.  Many psych meds can be helpful for neuropathic pain.  The basic serotonin mmeds aren't really one of them.  For pain, the SNRI's (cymbalta, effexor, prestiq, and there's another out now) are the primary first-line meds.  Then you have the TCA Amytriptyline (which is also commonly used).  Finally, the biggest fibro med that's classified as psych (but in a class all of it's own) is Lyrica.  Topamax is also sometimes used... but I'd refuse that one, personally.  For nausea, I take Zofran.  I highly recommend it above the others.
