My old pdoc never diagnosed bipolar and I think the Effexor is what switched me into mania. The pdoc at the hospital here is useless and was all for sending me to a homeless shelter after I'd been put on seroquel (a truly horrid concoction and then od'd). I wish I'd never even gone to a doctor. I am more depressed now than ever. Another time a GP put me on two meds, one of them Halcyon and it nearly killed me and made me psychotic. I was hauled off by the police!!!
So far I think meds have done more harm than good and I resent it!

Good luck to you.
