"i started taking cymbalta a year ago. side effects - nausea and pain in stomach. this was with 30mg. doctor recommended 60mg. it really worked but after about 4 months i just could not afford it so my doctor prescribed celexa. i used that for several months. i noticed that my usual mild lower back pain returned. (i suffered no withdrawal symptoms). i got back on cymbalta 2 months ago.  "
