I have been taking celexa 10-20mg for the past 8 years after my son was born and through my recent pregnancy for antenatal and post partum depression/anxiety. The psych just added Buspar 5mg 2-3 x daily. My question is should I take it 3x a day? How long will it take to feel an improvement? Does it work well with Celexa? Any side effects? I feel kinda tired after taking it.
