Yeah after I had the baby the nurse came to talk to me about what happened and said I had a bad reaction to the castor oil and that she's seen it happen before. Not sure if I believe it was the castor oil, I don't see it as being something so powerful like a drug to cause to me labor this way but who knows, I will never take it again.
I forgot to mention I was also vomiting uncontrollably. They gave me antinausea meds and it didn't help at all, i was miserable. Maybe that was from the castor oil.
