Help 1 month pp and.....

Sandra
Help I'm 1 month postpartum I've been exclusively breastfeeding and all I crave is Oreos I can eat the whole thing a day. I know it's bad and I have never liked Oreos like that. I use to eat three and I had enough and now I eat all of the bag and still don't have enough. Help please it started ever since my milk started coming down. I try so hard to stop but is like my body needs them. 
Any suggestions??
