"i have been on cymbalta for about four months. my doctor switched me from zoloft to cymbalta after i continued to experience panic attacks. fortunately, cymbalta worked great! my panic attacks went away and my mood swings seemed to calm down. but, about a month ago i decided that i wanted to come off of cymbalta because my husband and i are trying to get pregnant. that&#039;s when things went down hill. instead of tapering off of the medicine (which is not what my doctor said i would have to do) i just stopped cold turkey. i began to experience severe headaches, insomnia, nausea, tingling in my hands and face, i also began to hallucinate and the worst part has been the brain zaps."
