It may just be that effexor doesn't work that well for you. (Unless, there was some other even that took place.) I've had to bring up this issue before. I just brought it up plainly, and I did right when I started the session. That made it easier for me. It's kind of a scarey thing to mention at first, but it didn't turn out badly. It was much better getting it out of the way. I just straight out said, "I'm having SI urges, lately."
