"third week on viibryd--been on 40 mg for five days. i was on lexapro but it seemed to poop out or my post-partum depression was too much for the maximum dose. definitely did not like the diarrhea side effect as i have major stomach problems, but it does go away. i feel pretty good. before the viibryd i was experiencing weepiness and major panic attacks. feel much less depressed and anxious. it seems to be working. sleeping better too. i&#039;ve been on antidepressants for 20 years (zoloft, celexa, effexor, lexapro). hope this one keeps doing what it&#039;s doing."
