"i have been on multiple antidepressants for 15 years, most recently lexapro for 5 years and abilify for 9 months. the abilify made me gain 15 lbs. and i&#039;ve been flat on the lexapro, like it&#039;s not working as well as it used to. my doctor prescribed me viibryd after taking a genetic test to understand which antidepressant will work best for me. i started on 10mg for 7 days, and i&#039;m on my 5th out of 7 days on the 20mgs. so far my side effects have been minimal; a little diarrhea, some dizziness, kind of a &quot;stuffy head&quot; feeling. as long as i eat before taking it i feel okay. my mood has been much better and i&#039;m not as tired as i was on lexapro. so far so good!"
