"i suffered with severe anxiety, especially in social situations. i think mine was linked to coming off my pill and my hormones going crazy. i tried sertraline for two days and felt horrid - flu like symptoms, depression, nausea, fatigue! i then tried venlafaxine and after two weeks my anxiety had gone. it came back around the time of the month but this medicine has truly fixed me. i understand that different medicines work for different people but this saved my life."
