"had been on effexor xr for 5 years, and noticed as i progressed toward menopause, my depression was worsening.  i was just a shell of the person i was previously.  i went to my dr and was prescribed  viibryd.  within a week i noted some gradual changes.  it has been just short of a month, and i notice less sleepiness and concentration concerns.  i also have less anxiety, and my irritable bowel syndrome symptoms are lessening too.  so far i am very pleased with it."
