"for me it was awful.  i was on this pill for 7 days.  i went to the doctor today because my heart was beating so fast on these pills and i was paranoid, anxious, shaking, and very very bit**y.  i thought i was having a heart attack at work i was crying, it was awful. i went to the doctor and i couldn&#039;t get words out.  my pulse was 115 and blood pressure was high (never ever is) it just shot up. the doctor said i was having a panic attack and that it is due to the medication.  she took me off it and for the next 5 days i am on lorazepam 0.5mg (sedative to calm me down - take it at night) and switching me back to sertaline.  this was the worst experience of my life.  i thought i was going to end up in the er or dead."
