with my first child i got on Celexa while i was pregers. and i was on it nursing as well after i gave birth and i didn't notice anything. If your doctor says its ok....its ok, oh and one more thing to ponder.... if you could stop during pregnancy and breastfeeding....maybe you didn't need it any longer. at some point you won't need it, but you will never find out until you get off of it. now i understand about being on it now being postpartum but, its something to think of....depression,weight gain, problems sleeping, lack of sexual desire, irritability, and difficulty concentrating are all signs of a HORMONAL imbalance. You could also try a hormone balancing cream like the natural Prolief from Arbonne. Just a thought. I know a woman who could get off of Zoloft after her pregnancy because of the cream. Good luck
