"after taking cymbalta for 3 weeks i become gradually more nervous, by 4 and 1/2 weeks i felt like i was having a constant panic attack. i felt terrified all the time but i couldn&#039;t even tell you what i was terrified of. it was the most horrible feeling i&#039;ve ever experienced. my doctor insisted that i increase the dose but i refused. i finally argued with him and demanded to be taken off. i&#039;ve been looking for someone else that experienced a similar reaction."
