Loss of appetite - breastfeeding

Has anyone else experienced major loss of appetite whilst breastfeeding? Before birth, I was expecting my appetite to go through the roof, especially with sweet cravings, but I’ve experienced the complete opposite. Sometimes I’m forcing myself to eat in the evenings, mainly for the benefit of my baby/producing milk. But still seem to have an oversupply despite this. Weighed myself tonight and I’m a couple of pounds under my pre-pregnancy weight already (although my body is completely different now). Just wondering if anyone else has been feeling the same and whether this will carry on throughout my breastfeeding journey or whether this will phase out as time goes on..
