"i have taken zoloft for a while but i was packing on the pounds and noticed i was getting kind of irritable when i&#039;m normally very laid back. doc gave me 2 sample packs of viibryd to try. 10mg i had some stomach upset (mostly diarrhea) and an intense craving for sweets/carbs. these went away eventually. then up to the 20mg. i found that i had zero appetite and literally had to force myself to eat. normally i&#039;d be happy about this but my mood became so dark (weeping/angry). i got to the point where i couldn&#039;t handle it anymore and had to stop. hopefully it works better for you all! good luck! :)"
