"i started using viibryd about a week and a half ago.  first couple days great, no problem.  went up to 20 mgs and weird side effects have started.  i constantly feel like i am going to vomit.  my legs are cramping and feels like i worked really hard which i haven&#039;t.  i&#039;m in pretty good shape, trim usually.  i am so bloated that i look like i am 3 months pregnant.  i&#039;m going back to the prozac.  the side effects aren&#039;t worth it.
