"i suffer from depression. i have been on viibryd for 3 months. i take it at 6pm daily, and i&#039;m on 40mg/day. i previously failed celexa, lexapro (allergic to lexapro), and wellbutrin. i love viibryd- my moods are improved, i&#039;m slower to react to angry situations, and i&#039;m sleeping better. i&#039;m noticing a nice boost in my libido. one small side effect i have is that i get what is called &#039;brain zaps&#039;. it just feels like someone is shocking my head. quick, kind of annoying, but tolerable. i get this sometimes right before i take my daily dose- like the medicine is &#039;wearing off&#039;."
