I would be very leery of SSNRIs if you have a lot of trouble with mania. Wellbutrin threw me into my first manic/psychotic episode ever and opened a gateway of sorts that I still believe turned a subclinical case of bipolar into full-blown disease. I've never been the same since.

It obviously does a lot of people good or it wouldn't be on the market, but it and Effexor can really do a number on some people. I would just be very cautious about asking for it, is all.
