"diarrhea only lasted a day. i was pleasantly surprised how fast viibryd began working. i felt so much better not even five days into taking it, which never happens with me! i thought i had finally found a medication that worked after six years. about two months into taking it i had gained about ten pounds, my vision had gotten worse, my sex drive had gone from being very very high to literally nothing (took three months after i stopped taking for it to return), and my depression and anxiety were back in full swing.  it wasn&#039;t normal depression where everything is just boring and you&#039;re lethargic and what not, it was the angry, scary, unpredictable depression i&#039;ve only experienced from bad reactions to other medication in the past."
