"i have been taking viibryd 40mg for 6 weeks. from about the third day i felt an improvement in my mood and energy. but starting around week four my mood started to change for the worst. i was grumpy and had zero patience for anything. my husband, my two year old, my dog, the list went on. now at week six i&#039;m ready to jump out a window. i have a drs. appointment this upcoming week. i need to take myself off of this. i had high hopes for this back to square one."
