Peppermint effect on breastfeeding

So I am a ftm and didn't know about what not to eat during breastfeeding. I love peppermint bark this time of year its my little splurge. Well I noticed a huge drop in my supply after today and didn't know what to think. So I researched supply drop and bingo! Peppermint oil for in candy causes a massive supply drop. I still dont know if I just royally fucked my supply and its not going to return or if it will work its way back up when the mint is out of my system. All I know is that I might have to either get formula to supplement or pump like a mad woman to see if that brings it up. I'm feeling really stupid and annoyed with myself right now. And with the postpartum hormone rage going on I'm crying now.
