"i have only just begun taking viibryd, and after one pill i already notice a difference, love it, my doctor has always directed me to take my anti-depressants at night for one of the biggest side effects is drowsiness. i did have a little bit of a hard time falling asleep, i was taking 200mg zoloft for about 2 yrs and it just pooped out. i haven&#039;t had any side effects yet. i&#039;m very hopeful of this antidepressant. although i did have one side effect my  muscles feel like i ran a country mile. i&#039;m hoping this gets better as i adjust to taking higher doses."
