I just starting taking effexor xr and it has only been 2 nights and I feel dumbed down... Like my brain is sticking and I have to stop and think about what I was going to do or say. Almost like when you walk into a room and forget why you went in there to begin with. I am also on a med called trazadone for sleep . I have heard from several ppl and other Pdocs that the only thing that help BPD is DBT..
