Some of us find the risk of the med exposure to the baby to be unacceptable. I am not triggered very easily and I cycle slowly so the risk to me is acceptable going off meds. I can't speak for why musik is doing it, but I don't want to be on meds for my next pregnancy.

My OB thinks Lithium is practically harmless, but I find cardiovascular defects to be very scary to deal with so no Lithium in the first trimester for me! (I work with critically ill babies at my job)

I don't judge others for what they choose but I have to make the decision I can live with.
