have you tried taking a different anti depressant? I was on one before for PPD and it effected my sex drive, but I am currently on wellbutrin (it's during pregnancy) and it does not effect my sex drive at all! my current sex drive at this point in the pregnancy varies, I really like sex when I have it, but I don;t always want to start in the first place, because I am tired from the pregnancy and running around after my 3 other kid's all day!
