Opioids Pain management and Breastfeeding

[Aporia]

So I know there was someone on here that had loads of experience being on a pain management program while pregnant and breastfeeding. I'm not sure if she's still on here but I didn't know where else to find the information I was looking for. I know that short term use of opiod pain medications are safe, but I can't find any information for chronic pain patients (long term use).
