Hi! I have been taking Paxil for 20 years. I have recently been struggling w/ more intense anxiety and depression and irritability. I am switching from Paxil to Cymbalta, and am down from 30 mg of Paxil to 5 mg, and then up to 60 mg of Cymbalta. I feel like I am having a racing heart/palpitations. I am not sure if it's anxiety, Paxil withdrawal, side effects from Cymbalta, or there is something wrong with my heart. Has anyone switched from Paxil to Cymbalta (weaning off/increasing at same time.) If so, did you have any issues? Thank you so much!
