I was on Paxil before we started TTC DS and my doctor switched me to Celexa instead. He said he felt more comfortable with the Celexa than the Paxil. I'm not sure how it compares as far as safety though. I didn't have any problems from switching brands so maybe that's an option for you? DS was/is fine.
The only thing of note is that I wasn't able to produce any milk last time and I was told that it could have been tied to the meds I was on. I also had a rough delivery though and that could also have caused it. Or I could just be one of those women who can't make milk. I guess we'll see this time around. I just wanted to throw it out there though because no one told me at the time that it was a possibility that my milk production could be effected, I wish I had known.
