depression
"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't normal depression where everything is just boring and you're lethargic and what not, it was the angry, scary, unpredictable depression I've only experienced from bad reactions to other medication in the past."
