I have used intravenous dilaudid for 29weeks of my pregnancy. I had an addiction more mental then physical. I just wanted the feeling I didn't know how to pull away. I finally let it go. I decreased the amt I was taking until I no longer desired it. Im 32weeks now & have no problems at all don't even desire it but I wonder will my baby withdraw & will he be ok. I still have 8weeks to go. I will not relapse so hopefully I will have a strong healthy baby.
