Hi I am new to this site as well but I have recently changed my meds from 20mg of Paroxetine (seroxat) to treat PTSD and was given 150mg of Venoflaxine, after 3 weeks my personality began to change, i became insecure and paranoid, short tempered and angry, my PTSD seemed to have been magnified by the change in medication. I ahve now switched back to Paroxetine and my personality is reverting back to normal. I was wondering if anyone else has had similiar experiences with Paroxetine or venoflaxine.
