I was on cymbalta for a year than they switched it to wellbutrin because it was better for bipolar, had an allergic reaction to wellbutrin then went thru cymbalta witdradral, that was hell! worse then going thru herion withdrawal. after 2 weeks in couldn't take it anymore my doc put me on a weeks of worth of prozac, it stays in your system longer. i feel much better now. don't just stop taking ur cymbalta ur bound for some hellish experiences you do not/ can not handle. good luck!
