Was on zoloft prior to pregnancy and after my Dr suggested Pristiq instead of Zoloft. I feel ok on Pristiq but 7 months later have not lost hardly any pregnancy weight. Its crippling my self esteem. This was my 3rd baby. Never had this problem with Zoloft. Is this normal? Keep reading how a side effect is loss of appetite. I don't have loss of appetite, but I'm not overeating either.I joined a gym and exercise full on every day. I am now running a minimum of 5km daily as well as other exercise, but still no change. Apart from the general weight all over I have a full on bloated looking belly.
