"i attempted to switch from prozac (which i take in combination with lamictal and wellbutrin) to viibryd to get rid of the sexual side effects of prozac. despite my high hopes for the medicine, i got progressively worse while titrating from prozac to viibryd. after about a month, i sunk until a major depression and nearly had to be hospitalized, so i went back on prozac. viibryd seems to be working well for many other people, but unfortunately i&#039;m not one of them. no side effects from the viibryd, although i wasn&#039;t off prozac long enough to judge whether viibryd would be better in terms of sexual side effects."
